From: Tanmay Shah Date: Tue, 3 Mar 2026 23:51:28 +0000 (-0800) Subject: remoteproc: xlnx: Release mailbox channels on shutdown X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=21f2762acb5c082666495ebfee8d4a159f03bb07;p=thirdparty%2Fkernel%2Fstable.git remoteproc: xlnx: Release mailbox channels on shutdown Mailbox driver can't introduce shutdown callback, as it might endup closing mbox channels prematurely. By allowing the client driver to manage the shutdown process, it's ensured that mailbox channels are closed only when they are no longer needed.
