From: Baokun Li <hidden>
Date: 2021-06-18 02:15:30
Also in:
lkml
Subsystem:
hibernation (aka software suspend, aka swsusp), the rest, x86 architecture (32-bit and 64-bit) · Maintainers:
"Rafael J. Wysocki", Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen
Fixes the following W=1 kernel build warning(s):
arch/x86/power/cpu.c:76: warning: Function parameter or
member 'ctxt' not described in '__save_processor_state'
arch/x86/power/cpu.c:192: warning: Function parameter or
member 'ctxt' not described in '__restore_processor_state'
Signed-off-by: Baokun Li <redacted>
