Mediatek MT76x2u: wrong firmware binary name causes firmware load fail

Hi there!

I noticed lately that MT76x2u chipset's firmware changed from
"mt7662.bin" -> "mt7662u.bin" and
"mt7662_rom_patch.bin" -> "mt7662u_rom_patch.bin"

This is wrong. the kernel module asks for "mt7662.bin" and "mt7662_rom_patch.bin";

So, the current linux-firmware will not work and device firmware will fail.
