Hi MichaÅ,

Thanks for the patch set.

Would you mind fixing also the following issues raised by
checkpatch.pl?:

WARNING: Missing a blank line after declarations
#376: FILE: drivers/platform/x86/dell-wmi-led.c:64:
+ struct bios_args args;
+ args.length = length;

WARNING: Block comments use * on subsequent lines
#460: FILE: drivers/platform/x86/dell-wmi-led.c:148:
+ /* The Dell LED delay is based on 125ms intervals.
+ Need to round up to next interval. */

WARNING: Block comments use a trailing */ on a separate line
#460: FILE: drivers/platform/x86/dell-wmi-led.c:148:
+ Need to round up to next interval. */

WARNING: Comparisons should place the constant on the right side of the test
#463: FILE: drivers/platform/x86/dell-wmi-led.c:151:
+ if (0 == on_eighths)

WARNING: Comparisons should place the constant on the right side of the test
#470: FILE: drivers/platform/x86/dell-wmi-led.c:158:
+ if (0 == off_eighths)

The fixes could be placed in an incremental patch after this one.

Best regards,
Jacek Anaszewski
