Subject: USB: usbtest.c: unsigned retval makes ctrl_out return 0 in case of error
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f54fa84dda211f68f65002efa44142207c886c79;p=linux-beck.git

USB: usbtest.c: unsigned retval makes ctrl_out return 0 in case of error

In my quest to try and figure out why test 14 (control write) doesn't
work with my EZ-USB board, I noticed that sometimes testusb reported
no error even though the kernel log complained "byte 0 is 0 not 2" etc.
