Subject: [PATCH v2 02/12] regmap-irq: Remove unused type_reg_stride field
Date: Thu, 23 Jun 2022 22:14:10 +0100 [thread overview]
Message-ID: <20220623211420.918875-3-aidanmacdonald.0x0@gmail.com> (raw)
In-Reply-To: <20220623211420.918875-1-aidanmacdonald.0x0@gmail.com>
It appears that no chip ever required a nonzero type_reg_stride
and commit 1066cfbdfa3f ("regmap-irq: Extend sub-irq to support
non-fixed reg strides") broke support. Just remove the field.
