Commit 04324f44cb69 ("MIPS: Remove get_fs/set_fs") changed the access_ok
for strnlen_user to check the whole range, which broke some callers
of strndup_user(). Restore the old behaviour and just check the first byte.

ITE IT8688E chip for management.
This chips is also handled by drivers/hwmon/i87.c but as it is also used
by the firmware itself it needs an ACPI driver.
Unfortunately not all sensor registers are handled by the firmware and even
less are exposed via WMI.

I'd rather make it explicit by also adding
default y

'This commit' is not any better than 'This patch' and this sentence
makes no sense. I might be missing something, but how exactly does "the

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.[ RFC1925, 2.3 ]

I think ret should just go away.
Like this?
"return platform_register_drivers(sprd_drm_drivers,
ARRAY_SIZE(sprd_drm_drivers));"
Sure.
