Subject: mwifiex: print sleep_confirm cmd/response and power save events
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=363c1b4f75d7a8cec61b74ee163f1f315a56f639;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mwifiex: print sleep_confirm cmd/response and power save events

Sleep Confirm command is sent separately while other commands
are handled through cmd_pending_q. Print sleep_confirm cmd and
its response as well as power save events so that we have a
clearer picture of power save handshake in driver log.
