Re: [PATCH v4 01/19] x86/msr-index: Clean up bit defines for IA32_FEATURE_CONTROL MSR
by kbuild test robot
Hi Sean,
I love your patch! Yet something to improve:
[auto build test ERROR on tip/auto-latest]
[also build test ERROR on next-20191129]
[cannot apply to tip/x86/core kvm/linux-next v5.4]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

[PATCH] media: coda: jpeg: fix platform_get_irq.cocci warnings
by Julia Lawall
From: kbuild test robot <lkp(a)intel.com>
Error report is redundant because platform_get_irq() already prints an
error
Generated by: scripts/coccinelle/api/platform_get_irq.cocci
Fixes: fb3a8aa62186 ("media: coda: jpeg: add CODA960 JPEG encoder support")

The {} will need to be removed as well.

That's a common question that Rong or Philip can answer (I forgot what
the answer has been in the past). Rong/Philip, it may be good to have
a URL/link that I can point people to in the future, since it's a FAQ.

improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
