net: dsa: Simplify 'dsa_tag_protocol_to_str()'
There is no point in preparing the module name in a buffer. The format string can be passed diectly to 'request_module()'. This axes a few lines of code and cleans a few things: - max len for a driver name is MODULE_NAME_LEN wich is ~ 60 chars, not 128. It would be down-sized in 'request_module()' - we should pass the total size of the buffer to 'snprintf()', not the size minus 1 Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
