Subject: [PATCH 1/5] clk: renesas: div6: Use clamp() instead of clamp_t()
Date: Thu, 1 Apr 2021 15:01:34 +0200 [thread overview]
Message-ID: <2670c1e3c82a245666578cbbd1fb20d37932fd8e.1617281699.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1617281699.git.geert+renesas@glider.be>
As "div" is already "unsigned int", adding "U" suffixes to the constants
"1" and "64" allows us to replace the call to clamp_t() by a call to
clamp(). This removes hidden casts, and thus helps the compiler doing a
better job at type-checking.
