Subject: media: redrat3: use int type to store negative error codes
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ecba852dc9f4993f4f894ea1f352564560e19a3e;p=thirdparty%2Fkernel%2Fstable.git

media: redrat3: use int type to store negative error codes

Change "ret" from u8 to int type in redrat3_enable_detector() to store
negative error codes or zero returned by redrat3_send_cmd() and
usb_submit_urb() - this better aligns with the coding standards and
maintains code consistency.

No effect on runtime.
