Subject[PATCH] usb: gadget: udc: Remove useless variable assignment in xudc_read_fifo()
Date
This patch removes the unused variables assignment warning.
Value assigned to variable bufferspace is overwritten, before
it can be used. This makes such variable assignment useless.

Reported Coverity warning: UNUSED_VALUE
