From: Peng Fan Date: Thu, 22 Jan 2026 12:44:57 +0000 (+0800) Subject: ASoC: codec: Remove ak4641 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d7e1f9e84af460c5f1e5352eda8f036000cfcf0a;p=thirdparty%2Fkernel%2Flinux.git ASoC: codec: Remove ak4641 Since commit d6df7df7ae5a0 ("ARM: pxa: remove unused board files"), there has been no in-tree user of the AK4641 codec driver. The last user (HP iPAQ hx4700) was a non-DT PXA board file that instantiated the device via I2C board data; that code was removed as part of the PXA board-file purge. The AK4641 driver was introduced ~2011 and still probes only via the I2C device-ID table ('.id_table'), without an 'of_match_table', so there are no upstream Devicetree users to retain. With no in-tree users left, remove the driver.
