Subject: [PATCH 4.19 30/43] dmaengine: xilinx_dma: fix incompatible param warning in _child_probe()
Date: Fri, 15 Jan 2021 13:28:00 +0100 [thread overview]
Message-ID: <20210115121958.506620898@linuxfoundation.org> (raw)
In-Reply-To: <20210115121957.037407908@linuxfoundation.org>
From: Shravya Kumbham <shravya.kumbham@xilinx.com>
commit faeb0731be0a31e2246b21a85fa7dabbd750101d upstream.
In xilinx_dma_child_probe function, the nr_channels variable is
passed to of_property_read_u32() which expects an u32 return value
pointer. Modify the nr_channels variable type from int to u32 to
fix the incompatible parameter coverity warning.
Addresses-Coverity: Event incompatible_param.
Fixes: 1a9e7a03c761 ("dmaengine: vdma: Add support for mulit-channel dma mode")
