| Subject: spi/pxa2xx: use GFP_ATOMIC in sg table allocation |
| |
| From: Mika Westerberg <mika.westerberg@linux.intel.com> |
| |
| commit 5548f98c46538d1da04eff179a52e50537d11465 upstream. |
| |
| 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. |
