[PATCH v6] staging: sm750: Rename sm750_hw_cursor_* functions to snake_case

[Kloudifold]

sm750 driver has sm750_hw_cursor_* functions, which are named in
camelcase. Rename them to snake case to follow the function naming
convention.

- sm750_hw_cursor_setSize  => sm750_hw_cursor_set_size
- sm750_hw_cursor_setPos   => sm750_hw_cursor_set_pos
- sm750_hw_cursor_setColor => sm750_hw_cursor_set_color
- sm750_hw_cursor_setData  => sm750_hw_cursor_set_data
- sm750_hw_cursor_setData2 => sm750_hw_cursor_set_data2

The test robot did not report that the names were incorrect :(

Is that the name you use to sign documents?

thanks,

Delete the last two lines.

As Greg made you notice, it was not the Kernel Test Robot that had reported 
you an issue for which you decided to make a patch to fix it.

The reason you made this patch is because you know that the Linux kernel style 
guide wants developers to avoid camel-case symbols.

Before your "Signed-off-by" tag, you should only credit those tools and/or 
services (checkpatch.pl, Coccinelle, Smatch, Syzkaller/Syzbot, GCC, Clang, and 
so on) that had noticed that Linux has a problem that predates the first 
version of your patch and that your first version has the purpose to fix that 
problem.

You made this patch because _checkpatch_ had reported issues with camel-case 
improper use, so you decided to convert some names to snake-case. You are 
invited to credit only _checkpatch_ for you patch ("Reported by 
checkpatch.pl.").

That credit is part of the commit message so, when you credit that tool, put a 
blank line after the credit and before the "Signed-off-by" tag.

Instead, you should delete this blank line after your sign.

This is the place to credit the Kernel Test Robot for noticing that you made 
mistakes with v1 and that v2 is for fixing them.

Therefore, give credit here to the Robot:

Thanks,

Fabio

P.S.: Someone suggested to drop the "sm750_" prefix. I don't think you should 
do anything like this because I don't see "static" functions prefixed by 
"sm750_" in your patch. However, later you may check if they can be "static" 
and, if so, drop the prefix and make them "static" (in a follow up patch).
