A flaw in the Linux Kernel found. In the Linux kernel before 5.16.3, drivers/scsi/ufs/ufs-mediatek.c misinterprets the regulator_get return value (expects it to be NULL in the error case, whereas it is actually an error pointer). Reference: https://github.com/torvalds/linux/commit/3ba880a12df5aa4488c18281701b5b1bc3d4531a
