Hi,
(first of all, your subject could be a little more descriptive,
something like:
usb: gadget: mv_u3d: request_irq() after initializing UDC
as that would better detail what you're doing)
Nadezda Lutovinova [off-list ref] writes:
If IRQ occurs between calling request_irq() and mv_u3d_eps_init(),
then null pointer dereference occurs since u3d->eps[] wasn't
initialized yet but used in mv_u3d_nuke().
The patch puts registration of the interrupt handler after
initializing of neccesery data.
Found by Linux Driver Verification project (linuxtesting.org).
this looks like an important bug fix, it probably deserves a stable tag
here. Which commit introduce this problem? Otherr than that, commits
looks good.
