Description

From dmesg:
[ 11.717865] mt7915e_hif 0000:01:00.0: enabling device (0000 -> 0002)
[ 11.735907] mt7915e 0000:02:00.0: enabling device (0000 -> 0002)
[ 11.901753] mt7915e 0000:02:00.0: Direct firmware load for mediatek/mt7915_rom_patch.bin failed with error -2
[ 11.911678] mt7915e 0000:02:00.0: Falling back to sysfs fallback for: mediatek/mt7915_rom_patch.bin
[ 11.991635] mt7915e: probe of 0000:02:00.0 failed with error -12

Rolled back to r21599, where it works with the same config

Research direction

Start by comparing snapshots r21950 and r21599 for the mt7915e firmware-loading and probe path, then reproduce the reported dmesg failure with the same configuration. Done means the Belkin RT1800 loads mt7915e successfully on r21950 without the missing firmware and error -12 messages.
