Subject: staging: wilc1000: use short name for hif local variable in chip_wakeup()
X-Git-Tag: v5.15~4244^2~229
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5832cbe21c16f8a443d4dc0fbe34c1ba3e61093c;p=platform%2Fkernel%2Flinux-starfive.git

staging: wilc1000: use short name for hif local variable in chip_wakeup()

Make use of a shorter name for 'hif' variable to avoid possible 80
character checkpatch warning while the replacing hardcoded value with
macros in chip_wakeup().
