X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f4de946bdb379f543e3a599f8f048d741ad4a58e;p=thirdparty%2Fkernel%2Flinux.git

wifi: rtw89: ser: enable error IMR after recovering from L1

After recovering from L1, explicitly enable error IMR to ensure next
L1 SER (system error recovery) can work normally.
