Subject: [PATCH] usb: gadget: mv_u3d: fix sparse warnings
fix the following sparse warnings:
drivers/usb/gadget/mv_u3d_core.c:223:20: warning: context imbalance in 'mv_u3d_done' - unexpected unlock
drivers/usb/gadget/mv_u3d_core.c:1562:25: warning: context imbalance in 'mv_u3d_handle_setup_packet' - unexpected unlock
Note that the non-trivial sparse warnings
are left out of this commit due to lack of
HW to test:
drivers/usb/gadget/mv_u3d_core.c:906:42: warning: incorrect type in argument 2 (different address spaces)
drivers/usb/gadget/mv_u3d_core.c:906:42: expected void [noderef] <asn:2>*<noident>
drivers/usb/gadget/mv_u3d_core.c:906:42: got unsigned int *<noident>
