[PATCH v2 1/1] coresight: trbe: Fix return value check in arm_trbe_register_coresight_cpu()

[Zhen Lei <thunder.leizhen@huawei.com>]

The commit in the 'Fixes:' uses devm_kzalloc() to allocate platform data
memory instead of coresight_get_platform_data(), but forgot to update the
return value check code accordingly. Fix the incorrect return value check
for devm_kzalloc(), which returns NULL instead of ERR_PTR() when it fails.

Fixes: 4277f035d227 ("coresight: trbe: Add a representative coresight_platform_data for TRBE")
