Subject: [PATCH] serial: mxs-uart: fix Wvoid-pointer-to-enum-cast warning
Date: Thu, 10 Aug 2023 10:50:42 +0200	[thread overview]
Message-ID: <20230810085042.39252-1-krzysztof.kozlowski@linaro.org> (raw)

`devtype` is enum, thus cast of pointer on 64-bit compile test with W=1
causes:

  mxs-auart.c:1598:15: error: cast to smaller integer type 'enum mxs_auart_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
