Subject: net: ep93xx_eth: fix mismatch of request_mem_region in remove
Git-commit: 3df70afe8d33f4977d0e0891bdcfb639320b5257
Patch-mainline: 5.4-rc8
References: bnc#1151927 5.3.16

The driver calls release_resource in remove to match request_mem_region
in probe, which is incorrect.
Fix it by using the right one, release_mem_region.
