From: Gabriel Rondon Date: Mon, 30 Mar 2026 18:22:55 +0000 (+0100) Subject: staging: most: dim2: replace BUG_ON() in poison_channel() X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e87946666e47d4b6f615e9ba0075375493194810;p=thirdparty%2Fkernel%2Flinux.git staging: most: dim2: replace BUG_ON() in poison_channel() Replace BUG_ON() range check on ch_idx with a return of -EINVAL. BUG_ON() is deprecated as it crashes the entire kernel on assertion failure (see Documentation/process/deprecated.rst).
