Subject: [PATCH][next] usb: gadget: net2272: remove redundant variable irqflags
Date: Thu,  7 Mar 2024 10:51:35 +0000

The variable irqflags is being initialized and being bit-or'd with
values but it is never read afterwards. The variable is redundant
and can be removed.

Cleans up clang scan build warning:
drivers/usb/gadget/udc/net2272.c:2610:15: warning: variable 'irqflags'
set but not used [-Wunused-but-set-variable]
