[U-Boot] [PATCH v5 4/5] usb: Add nonblock argument to submit_int_msg
Michal Suchanek
msuchanek at suse.de
Sun Aug 18 08:55:27 UTC 2019
This will be used to implement non-blocking keyboard polling in case of
errors.
Signed-off-by: Michal Suchanek <msuchanek at suse.de>
---
v2: add missing hunk from last patch
v4:
- propagate nonblock argument to wrapper
- add documentation of nonblock argument to wrapper
v5:
- also propagate the extra argument to USB emulator
- wrap lines slightly over 80 characters
