[PATCH 0/2] *** staging: sm750fb: Rename maxH and maxW to max_h and max_w ***

[Benjamin Philip]

This patchset (as the subject implies) renames some struct members to follow the
snake_case naming convention from CamelCase. By doing so, it also fixes 2
checkpatch CHECKs.

To test it, I have only checked if the module builds, which it does.

Note: I am very new to the Linux Kernel. This is my first patch. I have done my best
to ensure that my patch is upto the expected standard and to research on what it is
expected by maintainers. Please forgive me if I have done something wrong.

Thanks,
Benjamin Philip

[PATCH 1/2] staging: sm750fb: Rename maxH to max_h in lynx_cursor

[Benjamin Philip]

The struct lynx_cursor has a member named maxH. This name is
CamelCase and is frowned upon. This commit renames it to max_h
and makes the necessary changes for the module to build.

This change also fixes the following checkpatch CHECK:

CHECK: Avoid CamelCase: <maxH>
