From: Simon Horman Date: Tue, 18 Apr 2023 11:07:33 +0000 (+0200) Subject: net: stmmac: dwmac-meson8b: Avoid cast to incompatible function type X-Git-Tag: v6.6.7~2736^2~95 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=43bb6100d8d5871d211196034042308c1b1d69c3;p=platform%2Fkernel%2Flinux-starfive.git net: stmmac: dwmac-meson8b: Avoid cast to incompatible function type Rather than casting clk_disable_unprepare to an incompatible function type provide a trivial wrapper with the correct signature for the use-case. Reported by clang-16 with W=1: drivers/net/ethernet/stmicro/stmmac/dwmac-meson8b.c:276:6: error: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict] (void(*)(void *))clk_disable_unprepare, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ No functional change intended. Compile tested only.
