Hi Julia,

Having reviewed previous messages on the mailing list, and running the command:
perl scripts/checkpatch.pl --strict -f drivers/staging/sm750fb/* | less

I found:
------------------------------------
drivers/staging/sm750fb/ddk750_dvi.c
------------------------------------
CHECK: Avoid CamelCase: <sii164GetDeviceID>
#19: FILE: drivers/staging/sm750fb/ddk750_dvi.c:19:

#22: FILE: drivers/staging/sm750fb/ddk750_dvi.c:22:

CHECK: Avoid CamelCase: <sii164SetPower>

#27: FILE: drivers/staging/sm750fb/ddk750_dvi.c:27:
+               .clear_interrupt = sii164ClearInterrupt,

total: 0 errors, 0 warnings, 8 checks, 62 lines checked

I would love to have all the 8 checks done, although I learnt it is one
check at a time.

Please how do I go about sending the patches, given the fact that same
definitions are
found in file: drivers/staging/sm750fb/ddk750_dvi.c and file:
drivers/staging/sm750fb/ddk750_sii164.h
and I don't know which other files they are defined.
