[PATCH] staging: sm750fb: fix naming conventions and remove dead code

[Hadi Chokr <hadichokr@icloud.com>]

Convert camelCase to snake_case to fix all checkpatch warnings.

Remove unused function sm750_hw_cursor_set_data2() and its declaration.

checkpatch warned that g_fbmode should be 'static const char * const';
this revealed that lynxfb_set_fbinfo() was writing back into g_fbmode
unnecessarily. Refactor to resolve the mode string into a local
const char * instead. Also drop the redundant NULL initializer since
static storage is zero-initialized.

Remove manual write to pdev->dev.power.power_state.event in
lynxfb_resume(); fb_set_suspend() already handles the resume state
correctly.
