[RESEND PATCH 0/6] Fix some coding style and comment problems.

[Tang Chen]

Fix some coding style and comment problems I saw when I was reading the code.

Tang Chen (6):
  acpi: Remove the leading space of "unlock" label in
    acpi_memory_device_notify().
  acpi: Add missing parameter comment for acpi_get_table_with_size().
  acpi: Remove the leading spaces of "finish_override" label in
    acpi_tb_table_override().
  acpi: Remove the leading spaces of "unmap_and_exit" label in
    acpi_tb_install_table().
  acpi: Add the missing parameter comment for acpi_initialize_tables().
  doc: Fix a wrong comment in Documentation/hw_random.txt

[RESEND PATCH 1/6] acpi: Remove the leading space of "unlock" label in acpi_memory_device_notify().

[Tang Chen]

There is a leading space in front of "unlock" label in acpi_memory_device_notify(). Remove it.

The leading space is actually in agreement with the kernel coding style
(and there's a reason why it's there).

Thanks,

Well, I'm curious. What's the reason ?
I didn't see anything in Documentation/CodingStyle about that.

Some tools had problems with labels starting right at the start of the line.
patch or diff or something similar IIRC.  That's not the case any more, but
there's a leading space before many labels in the kernel and that is part of
the coding style, actually, even if it is not documented.

Certainly, it's not something to fix.

Thanks,
Rafael

[RESEND PATCH 2/6] acpi: Add missing parameter comment for acpi_get_table_with_size().

[Tang Chen]

In the comment of acpi_get_table_with_size(), one parameter tbl_size
is missing. And the definitions of i and j begin with space, not tab.
