Subject: [PATCH 1/1] coresight: trbe: Fix return value check in arm_trbe_register_coresight_cpu()

Function devm_kzalloc() returns NULL instead of ERR_PTR() when it fails.
The IS_ERR() test in the return value check should be replaced with NULL
test.

Fixes: 39744738a67d ("coresight: trbe: Allocate platform data per device")
Fixes: 3fbf7f011f24 ("coresight: sink: Add TRBE driver")
