Sorry, I'm trying to start contributing in the kernel. I run

scripts/checkpatch.pl --file drivers/staging/sm750fb/*.c

And the output was:

drivers/staging/sm750fb/sm750.c
-------------------------------
WARNING: static const char * array should probably be static const char

#36: FILE: drivers/staging/sm750fb/sm750.c:36:

CHECK: Avoid CamelCase: <setAllEngOff>
#863: FILE: drivers/staging/sm750fb/sm750.c:863:
+ sm750_dev->init_parm.setAllEngOff = 0;

total: 0 errors, 1 warnings, 2 checks, 1171 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
mechanically convert to the typical style using --fix or
--fix-inplace.

So I tried to change pvReg for pv_reg and the same for setAllEngOff.

As I understand the test robot failed because:


drivers/staging/sm750fb/sm750_hw.c: In function 'hw_sm750_map':
>> drivers/staging/sm750fb/sm750_hw.c:43:13: error: 'struct sm750_dev' has no member named 'pvReg'; did you mean 'pv_reg'?
sm750_dev->pvReg =
^~~~~
pv_reg

So, in this v2 I added sm750_hw.c.

Please let me know if I misunderstood the workflow
