Modified files:
sys/dev/usb uhci.c
Log:
Remove some strange code that allocates memory and then immediately
frees it again. The idea was to perform M_WAITOK allocations in a
process context to reduce the risk of later interrupt-context
M_NOWAIT allocations failing, but in fact this code can be called
from contexts where it is not desirable to sleep (e.g. if_start
routines), so it causes lots of witness "could sleep" warnings.
