Subject: [PATCH v3 02/10] pinctrl: cy8c95x0; Switch to use for_each_set_clump8()
Date: Wed,  5 Feb 2025 11:51:12 +0200	[thread overview]
Message-ID: <20250205095243.512292-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20250205095243.512292-1-andriy.shevchenko@linux.intel.com>

for_each_set_clump8() has embedded check for unset clump to skip.
Switch driver to use for_each_set_clump8().
