Use the below scripts to check:
scripts/checkpatch.pl -f --subject arch/arm/mach-rockchip/platsmp.c
Although there is a check, it's no matter.

CHECK: usleep_range is preferred over udelay; see
Documentation/timers/timers-howto.txt
+167udelay(10);
total: 0 errors, 0 warnings, 1 checks, 362 lines checked

 Changes in v4:
    - Add reset_control_put(rstc) for the non-error case.
    - Fix commit information in PATCH [1/3]

 Changes in v3:
    - FIx the PATCH v2, it doesn't work on chromium 3.14.

 Changes in v2:
    - As Kever points out, Fix the subject typo WIF/WFI in PATCH [2/3].
    - As Heiko suggestion, re-adjust the cpu on/off flow in PATCH [1/3].
    - Use the checkpatch.pl -f --subjective to check in PATCH [3/3].
