[PATCH net-next v2 6/7] netconsole: improve code style in parser function

From: Breno Leitao
Date: Wed Jun 11 2025 - 10:23:23 EST


Split assignment from conditional checks and use preferred null pointer
check style (!delim instead of == NULL) in netconsole_parser_cmdline().
This improves code readability and follows kernel coding style
conventions.
