6.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jiri Slaby <[email protected]> [ Upstream commit d3352ab0a9701a6d4c88b814815d7320c339f4a8 ] 'source' is the same as 'buf'. Rename the parameter ('buf') to 'source' and drop the local variable. Likely, the two were introduced to have a different type. But 'char' and 'unsigned char' are the same in the kernel for a long time.
