Dirk? Also, the patch seems to have some issue. The checkpatch.pl through the below error. ERROR: patch seems to be corrupt (line wrapped?) #42: FILE: drivers/mmc/host/omap_hsmmc.c:440: struct mmc_command *cmd, total: 1 errors, 0 warnings, 123 lines checked sdio/OMAP35xx.patch has style problems, please review. If any of these errors are false positives report them to the maintainer, see CHECKPATCH in MAINTAINERS. > > -------- Original Message -------- > From: Phaneedra Kumar Alapati <phani@xxxxxxxxxxx> > To: linux-omap@xxxxxxxxxxxxxxx <linux-omap@xxxxxxxxxxxxxxx> > CC: phani@xxxxxxxxxxx <phani@xxxxxxxxxxx> > Date: Thu, 10 Dec 2009 08:24:57 +0100 > Subject: [PATCH]OMAP35xx:SDIO IRQ Support for OMAP35xx > Thread-Topic: [PATCH]OMAP35xx:SDIO IRQ Support for OMAP35xx > Thread-Index: Acp5aeARQUQJtw2USfCUiuj07cawqQ== > Message-ID: <8B7FC6A3798741D6B3E3284E1A8D7A27@embwise16de1b5> > > This patch adds SDIO IRQ support for OMAP35xx.
