Subject: [PATCH 12/22] staging: emxx_udc: Don't use GFP_DMA when calling dma_alloc_coherent()
Date:   Sat, 19 Feb 2022 08:52:11 +0800
Message-Id: <20220219005221.634-13-bhe@redhat.com>
In-Reply-To: <20220219005221.634-1-bhe@redhat.com>
References: <20220219005221.634-1-bhe@redhat.com>
Precedence: bulk

dma_alloc_coherent() allocates dma buffer with device's addressing
limitation in mind. It's redundent to specify GFP_DMA when calling
dma_alloc_coherent().
