staging/quatech_usb2: remove unused qt2_box_flush function
PATCH 1/1 staging/quatech_usb2: remove unused qt2_box_flush function
Hello,
In today linux-next I got a compilation warning:
drivers/staging/quatech_usb2/quatech_usb2.c:1852: warning: ‘qt2_box_flush’ defined but not used
Since -next is an integration three, maybe this function is going to be used. But anyway I send a patch that fix the warning removing the qt2_box_flush function just in case.
Thanks a lot.
Javier
