From 3ff79e76d31f32575fbd8a8ad6ce9108ca916d1a Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 26 Nov 2025 19:22:59 +0100 Subject: [PATCH] i2c: pxa: Fix Wvoid-pointer-to-enum-cast warning 'i2c_types' is an enum, thus cast of pointer on 64-bit compile test with clang and W=1 causes: i2c-pxa.c:1269:15: error: cast to smaller integer type 'enum pxa_i2c_types' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] One of the discussions in 2023 on LKML suggested warning is not suitable for kernel. Nothing changed in this regard since that time, so assume the warning will stay and we want to have warnings-free builds.
