[PATCH 0/5] staging: rts5208: clean up coding style in rtsx_chip.c

[Giedrius Statkevicius]

From: Giedrius Statkevičius <giedrius.statkevicius@gmail.com>

Align divided lines to the first line's opening paranthesis
Where two or more if's are in form 'if (a) if (b) { [...] }' convert them into one to lower the indentation level.
Use the ternary operator in places where there is code in format of: 'if (a) { b = foo1; } else { b = foo2; }'
Make the names of labels all lower case to avoid Camel Case.
Remove unnecessary parantheses around variables that are after a dereference operator like this: '&(a) => &a'
Switch the if condition around in 'if (0 == (value & (1 << bit))) {' to make it have the same form as the rest of the code.

After this patch checkpatch.pl without --strict doesn't complain about rtsx_chip.c at all and with --strict it only complains about the unmatched parantheses. I am reluctant to move that code with unmatched parantheses into another function to lower the indentation level because I don't have the hardware needed to test this driver and don't have enough experience to do it properly. Doing so would just probably hide the other problems this code has. My patch is purely about changing the code style without creating more functions and moving code to them. 

This patch is against Greg KH's staging-next tree.

Giedrius Statkevičius (5):
  Combine ifs into one where possible to avoid unnecessary indentation
    level increase
  Convert Camel Case labels to lower case, remove unnecessary
    parantheses after a dereference operator and remove empty lines
    before }
  Align lines of divided lines to the opening paranthesis where
    possible
  Divide lines to make them less than 80 characters long, align to the
    opening paranthesis where possible
  Use ternary operators where possible and sensible to avoid unnecessary
    increase of indentation level

[PATCH 0/5] staging: rts5208: clean up coding style in rtsx_chip.c

[Giedrius Statkevicius]

From: Giedrius Statkevičius <giedrius.statkevicius@gmail.com>

This patch set is a general code style clean up for rtsx_chip.c. After
this patch set checkpatch.pl without --strict doesn't complain anything
about at all and with --strict it only complains about unmatched
parantheses in those few places where I can't fix them because I don't
have the hardware to test the bigger changes nor do I have enough
experience to make such bigger changes flawlessly.

[PATCH 1/5] staging: rts5208: combine ifs where possible

[Giedrius Statkevicius]

From: Giedrius Statkevičius <giedrius.statkevicius@gmail.com>

Join together chained if's where possible to lower the indentation
level.

In a lot of places of this code the indentation level is already very
high.
As a result, this patch increases the code flow and readability.

[PATCH 2/5] staging: rts5208: get rid of Camel Case, remove unneeded lines and parantheses

[Giedrius Statkevicius]

From: Giedrius Statkevičius <giedrius.statkevicius@gmail.com>

Convert labels from Camel Case to lower case, remove unnecessary
parantheses around operands of dereference operators and remove unneeded
empty lines before }.

Gets rid of a checkpatch.pl "check" that code should avoid Camel Case,
also the code had a bunch of &(a) where a is some variable so it gets
rid of them too.  Finally, in a few places there were a empty line
before } so remove them.

[PATCH 3/5] staging: rts5208: align divided lines to opening paranthesis

[Giedrius Statkevicius]

From: Giedrius Statkevičius <giedrius.statkevicius@gmail.com>

Make all divided lines aligned to the opening paranthesis.

Basically makes all lines aligned to the opening paranthesis to make the
code more readable and it also gets rid of a lot of checkpatch.pl
"checks".

[PATCH 4/5] staging: rts5208: divide lines to make them less than 80 characters long

[Giedrius Statkevicius]

From: Giedrius Statkevičius <giedrius.statkevicius@gmail.com>

Make a couple of lines shorter than the max limit by diving them and
also make sure to align them properly where possible.

[PATCH 5/5] staging: rts5208: use ternary operators to reduce indentation level

[Giedrius Statkevicius]

From: Giedrius Statkevičius <giedrius.statkevicius@gmail.com>

Convert code in format of if (a) if(b) { [...] } to one line with a
simple ternary operation to avoid unnecesary increase of indentation
level.

[PATCH 0/5] staging: rts5208: clean up coding style in rtsx_chip.c

[Giedrius Statkevicius]

From: Giedrius Statkevičius <giedrius.statkevicius@gmail.com>

This patch set is a general code style clean up for rtsx_chip.c. After
this patch set checkpatch.pl without --strict doesn't complain anything
about at all and with --strict it only complains about unmatched
parantheses in those few places where I can't fix them because I don't
have the hardware to test the bigger changes nor do I have enough
experience to make such bigger changes flawlessly.

(Sorry for littering the mailing list. You can delete my other threads.
I somehow accidentaly managed to reply to my older thread. This is
really embarassing.)

Giedrius Statkevičius (5):
  staging: rts5208: combine ifs where possible
  staging: rts5208: get rid of Camel Case, remove unneeded lines and
    parantheses
  staging: rts5208: align divided lines to opening paranthesis
  staging: rts5208: divide lines to make them less than 80 characters
    long
  staging: rts5208: use ternary operators to reduce indentation level
