Hello,
I found a bug in the driver myrb when probing the module.
The following log can reveal it:
[ 0.985741] myrb 0000:00:05.0: Unknown Initialization Error 49
[ 0.986078] myrb 0000:00:05.0: Failed to initialize Controller
[ 0.986376] BUG: kernel NULL pointer dereference, address: 0000000000000000
[ 0.987368] Call Trace:
[ 0.987368] myrb_cleanup+0x4ad/0x7b0
[ 0.987368] myrb_probe.cold+0x95/0x12a0
The reason is that the driver does not initialize the disable_intr,
resulting in a null-pointer-dereference bug.
