Subject: [PATCH 2/2] Input: xpad - drop checks for XTYPE_UNKNOWN
Date: Tue, 16 Nov 2021 17:25:06 +0100	[thread overview]
Message-ID: <20211116172506.234dbf1d@rechenknecht2k11> (raw)
In-Reply-To: <3b25f4b1-3ec0-0878-99bc-0da06ce7c2f2@gmail.com>

If xtype is XTYPE_UNKNOWN, it will *always* be replaced by the real
detected type in xpad_probe().

It is therefore not possible to encounter the xtype == XTYPE_UNKNOWN
condition anywhere at the run-time of the driver.

That means we can drop those checks.
