[ Upstream commit a9e1b0ec5bdeedcf062416af4081aa005f8bf1e7 ]
After firmware boots, it reads keys info from efuse and checks secure checksum, but suddenly failed to access efuse resulting in probe failure, and driver throws messages:
rtw89_8852be 0000:03:00.0: fw security fail rtw89_8852be 0000:03:00.0: download firmware fail rtw89_8852be 0000:03:00.0: [ERR]fwdl 0x1E0 = 0xe2 rtw89_8852be 0000:03:00.0: [ERR]fwdl 0x83F0 = 0x210090
Retry five times to resolve rare abnormal hardware state.
