Re: [PATCH v2 6/6] dell-led: move driver to drivers/platform/x86/dell-wmi-led.c

Show key headers only | View raw

Hi Michał,

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
