Subject: drm/i915: Put fixed modes directly onto the panel's fixed_modes list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: db10c14a2523071369e87c24af854928d52dad34
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Rather than having the connector init get the fixed mode back from
intel_panel and then feed it straight back into intel_panel_init()
let's just make the fixed mode lookup put the mode directly onto
the panel's fixed_modes list. Avoids the pointless round trip and
opens the door for further enhancements to the fixed mode handling.
v2: Make the debug message correct by using intel_panel_drrs_type() (Jani)
