When CONFIG_DVB_DYNAMIC_MINORS is not enabled, clang warns (or errors with CONFIG_WERROR=y): drivers/media/dvb-core/dvbdev.c:554:10: warning: variable 'ret' is uninitialized when used here [-Wuninitialized] 554 | return ret; | ^~~ Use the return code -EINVAL directly, like the CONFIG_DVB_DYNAMIC_MINORS block does.
