X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=af1e82232b988f8fc6d635c60609765e49221a64;p=thirdparty%2Fkernel%2Flinux.git

wifi: rtw89: pci: restore LDO setting after device resume

The LDO (Low Dropout Regulator) setting is missing after suspend/resume
in some platforms, and it will cause card loss. Therefore, reconfigure
this setting to avoid it.
