Subject: Re: [PATCH v2] usb: host: oxu210hp-hcd: Fix potential deadlock on &oxu->mem_lock

Thank you for pointing out the formatting error in the patch.

Truly only building testing is performed as mentioned in commit but
no hardware testing was able to be performed. The bug was detected
by tool and also reviewed by myself, I thought it could be a real issue
so I send the patch to fix it by using safer irq-variant locking API.

I understand the guideline and appreciate it. Would be grateful if anyone
who has written/is familiar with the driver could review whether this is
a real bug and whether it should be fixed.

Best,
Chengfeng
