Commit Message

Pawel Laszczak Oct. 15, 2020, 4:54 a.m. UTC 
On failure, the platform_get_irq_byname prints an error message,
so patch removes error message related to this function from
core.c file.

A change was suggested during reviewing CDNSP driver by Chunfeng Yun.

Changelog:
v4
- fixed typo.
- "Acked-by" tag has been added.
v3
- changed error condition checking for dev_irq.
v2
- simplified code as sugested by Roger Quadros.
