[PATCH -next v2 2/5] misc: microchip: pci1xxxx: Fix missing spin_lock_init()

From: Wei Yongjun
Date: Wed Sep 07 2022 - 10:41:34 EST


From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

Fixes: 7d3e4d807df2 ("misc: microchip: pci1xxxx: load gpio driver for the gpio controller auxiliary device enumerated by the auxiliary bus driver.")
