Subject: [PATCH 03/11] staging: speakup: Simplify "NULL" comparisons
Date: Tue, 21 Mar 2017 17:12:27 +0530	[thread overview]
Message-ID: <20170321114235.1638-4-arushisinghal19971997@gmail.com> (raw)
In-Reply-To: <20170321114235.1638-1-arushisinghal19971997@gmail.com>

Fixed coding style for null comparisons in speakup driver to be more
consistant with the rest of the kernel coding style.
Replaced 'x != NULL' with 'x' and 'x = NULL' with '!x'.

Signed-off-by: Arushi Singhal <arushisinghal19971997@gmail.com>
