From 04a894417812c85e5f21d3637dc5632edaf2cdff Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Thu, 20 Oct 2022 16:48:16 +0200 Subject: [PATCH] generic: 5.15: backport smempart parser fixup patch with EPROBE_DEFER error Backport patch from kernel 5.15 that mute error on EPROBE_DEFER with smempart parser. This parser require the smem device to be probed first and currently it may happen that mtd gets probed before the smem device causing an error on the smempart parser. This error may be confusing and should be muted.
