From 5548f98c46538d1da04eff179a52e50537d11465 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Tue, 18 Jun 2013 17:29:44 +0300 Subject: [PATCH] spi/pxa2xx: use GFP_ATOMIC in sg table allocation pxa2xx_spi_map_dma_buffer() gets called in tasklet context so we can't sleep when we allocate a new sg table. Use GFP_ATOMIC here instead.
