Subject: USB: atmel-usba-udc : fix control out requests.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f42706c90470851fd2e97eda7a4109e8949bde8a;p=linux-beck.git

USB: atmel-usba-udc : fix control out requests.

usbtest #14 was failing with "udc: ep0: TXCOMP: Invalid endpoint state 2, halting endpoint..."
This occured since ep0 is bidirectional and ep->is_in is not valid (must always use ep->state)
