Subject: [PATCH] ASoC: q6dsp: fix event handler prototype
Date: Tue, 13 Feb 2024 11:10:46 +0100 [thread overview]
Message-ID: <20240213101105.459402-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
clang-16 points out a mismatch in function types that was hidden
by a typecast:
sound/soc/qcom/qdsp6/q6apm-dai.c:355:38: error: cast from 'void (*)(uint32_t, uint32_t, uint32_t *, void *)' (aka 'void (*)(unsigned int, unsigned int, unsigned int *, void *)') to 'q6apm_cb' (aka 'void (*)(unsigned int, unsigned int, void *, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
355 | prtd->graph = q6apm_graph_open(dev, (q6apm_cb)event_handler, prtd, graph_id);
sound/soc/qcom/qdsp6/q6apm-dai.c:499:38: error: cast from 'void (*)(uint32_t, uint32_t, uint32_t *, void *)' (aka 'void (*)(unsigned int, unsigned int, unsigned int *, void *)') to 'q6apm_cb' (aka 'void (*)(unsigned int, unsigned int, void *, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
499 | prtd->graph = q6apm_graph_open(dev, (q6apm_cb)event_handler_compr, prtd, graph_id);
The only difference here is the 'payload' argument, which is not even
used in this function, so just fix its type and remove the cast.
Fixes: 88b60bf047fd ("ASoC: q6dsp: q6apm-dai: Add open/free compress DAI callbacks")
