[alsa-devel] [PATCH 1/2] slimbus: qcom-ctrl: fix a NULL test

"retries" ends when it is set to -1 and not 0 so that part of the test is wrong. This bug would lead to a NULL dereference a couple lines later.

Fixes: afbdcc7c384b ("slimbus: Add messaging APIs to slimbus framework") Signed-off-by: Dan Carpenter dan.carpenter@oracle.com --- Should Greg be added to the MAINTAINERS file for this driver?
