Subject: [PATCH v2 1/3] staging: most: dim2: replace IS_ERR_OR_NULL with IS_ERR for devm_clk_get
Date: Mon, 23 Feb 2026 21:09:48 +0000	[thread overview]
Message-ID: <20260223210950.1900-2-iprintercanon@gmail.com> (raw)
In-Reply-To: <20260223210950.1900-1-iprintercanon@gmail.com>

devm_clk_get() never returns NULL, so IS_ERR_OR_NULL() checks are
unnecessary. Replace them with IS_ERR() for both the "mlb" and
"pll8_mlb" clock lookups in fsl_mx6_enable().
