[PATCH] staging: vt6656: Move firmware functions into main_usb.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The firmware function are not that complicated so
move them into main_usb as static functions in callers
visibility

Firmware definitions moved to device.h and MODULE_FIRMWARE
move to below module_usb_driver.
