Subject: staging: r8188eu: remove change_rfpwrstate
X-Git-Tag: v6.6.7~3436^2~21
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0fb449c5749ce5a6238a53f69bf178405862473e;p=platform%2Fkernel%2Flinux-starfive.git

staging: r8188eu: remove change_rfpwrstate

Remove the change_rfpwrstate component in struct pwrctrl_priv.

change_rfpwrstate is set to rf_off directly before each ips_enter call and
then checked in ips_enter. This makes no sense.

change_rfpwrstate might have been used to avoid conflicts between
suspend and resume operations. If a driver has to do this at all,
pwrpriv->ps_processing will do this job.
