[PATCH 0/3] Fix NULL pointer dereference in RZ/{G2L,V2M,A2} pinctrl driver

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

Fix NULL pointer dereference in RZ/{G2L,V2M,A2M} pinctrl driver due to
a race condition during boot. We have seen issues with RZ/{G2L,V2M} boards.
Based on the code, RZ/A2 will also hit this issue. So fixing RZ/A2 aswell.

This issue is reproducible with 1/200 reboots.
