Subject: rndis_wlan: use power save only for BCM4320b
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=63453c05da685323d45b7063cc27cf5e44b4134c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rndis_wlan: use power save only for BCM4320b

BCM4320a breaks when enabling power save (bug 29732). So disable power save
for anything but BCM4320b that is known to work.
