Subject: [PATCH 1/3] mfd: max14577: Fix Wvoid-pointer-to-enum-cast warning (again)
Date: Thu,  6 Jun 2024 16:36:46 +0200
Message-ID: <20240606143648.152668-1-krzysztof.kozlowski@linaro.org>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

'type' is an enum, thus cast of pointer on 64-bit compile test with
clang and W=1 causes:

  max14577.c:400:23: error: cast to smaller integer type 'enum maxim_device_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

Year ago this was solved, although LKML discussion suggested warning is
not suitable for kernel.  Nothing changed in this regard for a year, so
assume the warning will stay and we want to have warnings-free builds.
