Bug Description
[Impact]
On a Dell laptop, When we do suspend/resume test, we found the
realtek wifi couldn't work after resume, from the dmesg, we found
the error log as below:
Log:
三 05 15:08:02 u-Precision-3591 kernel: rtw89_8852be 0000:02:00.0: fw security fail
三 05 15:08:02 u-Precision-3591 kernel: rtw89_8852be 0000:02:00.0: download firmware fail
三 05 15:08:02 u-Precision-3591 kernel: rtw89_8852be 0000:02:00.0: [ERR]fwdl 0x1E0 = 0x62
三 05 15:08:02 u-Precision-3591 kernel: rtw89_8852be 0000:02:00.0: [ERR]fwdl 0x83F2 = 0x8
[Fix]
Backport a commit from mainline kernel (linux-next), this will retry firmware
loading for 5 times.
[Test Case]
run suspend/resume test case for over 100 times, the wifi still
works.
[Where problems could occur]
This commit comes from mailine kernel, and it doesn't change existing
driver except loading firmware a couple of more times if there is an error.
In theory this will not introduce regression.
