Subject: [PATCH v2 7/7] Input: do not check number of events in input_pass_values()
Date: Wed, 3 Jul 2024 14:37:54 -0700 [thread overview]
Message-ID: <20240703213756.3375978-8-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20240703213756.3375978-1-dmitry.torokhov@gmail.com>
Now that the input_dev->vals array is always there we can be assured
that input_pass_values() is always called with a non-0 number of
events. Remove the check.
