[PATCH] regulator: da9063: remove redundant return statement
From: Rishi Gupta
Date: Wed Feb 05 2020 - 23:36:19 EST
The devm_request_threaded_irq() already returns 0 on success
and negative error code on failure. So return from this itself
can be used while preserving error log in case of failure.
This commit also fixes checkpatch.pl errors & warnings:
- WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
- WARNING: line over 80 characters
- ERROR: space prohibited before that ',' (ctx:WxW)
- ERROR: code indent should use tabs where possible
- WARNING: Block comments use * on subsequent lines
