Subject: [PATCH 15/22] usb: cdns3: Don't use GFP_DMA32 when calling dma_pool_alloc()
Date:   Sat, 19 Feb 2022 08:52:14 +0800
Message-Id: <20220219005221.634-16-bhe@redhat.com>
In-Reply-To: <20220219005221.634-1-bhe@redhat.com>
References: <20220219005221.634-1-bhe@redhat.com>
Precedence: bulk

dma_pool_alloc() uses dma_alloc_coherent() to pre-allocate DMA buffer,
so it's redundent to specify GFP_DMA32 when calling.
