Subject: [PATCH v2 4/4] drm/etnaviv: Simplify clock enable/disable
Date: Sat, 23 May 2020 12:41:37 +0200 [thread overview]
Message-ID: <20200523104137.12562-5-lkundrak@v3.sk> (raw)
In-Reply-To: <20200523104137.12562-1-lkundrak@v3.sk>
All the NULL checks are pointless, clk_*() routines already deal with NULL
just fine.
