[PATCH] USB / dwc3: fix checkpatch warnings

From: Kushagra Verma
Date: Sun May 01 2022 - 09:17:04 EST


This patch fixes the following checkpatch warnings in core.c and
core.h:
1. WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
2. WARNING: Possible unnecessary 'out of memory' message
3. WARNING: No space before tabs

It also changes 'Error to get property' to 'Couldn't get property' in
dev_err() as the latter one is more meaningful.
