From: Gabriel Rondon Date: Mon, 30 Mar 2026 18:22:54 +0000 (+0100) Subject: staging: most: dim2: replace BUG_ON() in enqueue() X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e922cb40026c7ab788d1955f8977e354167f6496;p=thirdparty%2Fkernel%2Flinux.git staging: most: dim2: replace BUG_ON() in enqueue() 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).
