Subject: [PATCH] ASoC: adau1977: Fix truncation warning on 64 bit architectures
Date: Fri, 1 Aug 2014 17:19:39 +0100 [thread overview]
Message-ID: <1406909979-12990-1-git-send-email-broonie@kernel.org> (raw)
From: Mark Brown <broonie@linaro.org>
Negating ADAU1977_BLOCK_POWER_SAI_LDO_EN creates an unsigned long constant
with all bits set which on 64 bit architectures needs to be truncated to
an unsigned int, generating a warning. Add an explicit cast since we know
this is OK.
