X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7400adae8d86dde3c60752bf66d487aa1b138bc1;p=openwrt%2Fstaging%2Faparcar.git

kernel: Add missing devm_regulator_get_exclusive()

This backports a patch from Linux 5.10.116 to fix a compile problem
introduced in 5.10.114.

drivers/usb/phy/phy-generic.c could not find
devm_regulator_get_exclusive().

+Subject: [PATCH] regulator: consumer: Add missing stubs to
+ regulator/consumer.h
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 51dfb6ca3728bd0a0a3c23776a12d2a15a1d2457 upstream.
+
+Add missing stubs to regulator/consumer.h in order to fix COMPILE_TEST
+of the kernel. In particular this should fix compile-testing of OPP core
+because of a missing stub for regulator_sync_voltage().
