6.9-stable review patch. If anyone has any objections, please let me know.

From: Chen Ni <nichen@xxxxxxxxxxx>
[ Upstream commit 413bf4e857fd79617524d5dcd35f463e9aa2dd41 ]
devm_ioremap() doesn't return error pointers, it returns NULL on error.
Update the check accordingly.
Fixes: e86bd43bcfc5 ("watchdog: sa1100: use platform device registration")
