From 1d1baefacdb48c81b8bf389265a4c3072c9aa08a Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Wed, 10 May 2023 14:32:17 +0200 Subject: [PATCH] i2c: mchp-pci1xxxx: Avoid cast to incompatible function type [ Upstream commit 7ebfd881abe9e0ea9557b29dab6aa28d294fabb4 ] Rather than casting pci1xxxx_i2c_shutdown to an incompatible function type, update the type to match that expected by __devm_add_action. Reported by clang-16 with W-1: .../i2c-mchp-pci1xxxx.c:1159:29: error: cast from 'void (*)(struct pci1xxxx_i2c *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict] ret = devm_add_action(dev, (void (*)(void *))pci1xxxx_i2c_shutdown, i2c); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/linux/device.h:251:29: note: expanded from macro 'devm_add_action' __devm_add_action(release, action, data, #action) ^~~~~~ No functional change intended. Compile tested only.
