Subject: [PATCH v1 3/7] xhci: mem: Get rid of redundant 'else'
Date: Mon,  6 Feb 2023 18:10:45 +0200	[thread overview]
Message-ID: <20230206161049.13972-4-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20230206161049.13972-1-andriy.shevchenko@linux.intel.com>

In the snippets like the following

	if (...)
		return / goto / break / continue ...;
	else
		...

the 'else' is redundant. Get rid of it.

While at it, make if chain sorted from testing bigger values to smaller.
