From 80412ca8abf087354891108d2f888ad3de56e73c Mon Sep 17 00:00:00 2001 From: Andreas Fenkart Date: Sat, 8 Nov 2014 15:33:17 +0100 Subject: mmc: omap_hsmmc: remove unused slot_id parameter omap_hsmmc only supports one slot. So slot id is always zero, and slot id was never used in the callbacks anyway Acked-by: Tony Lindgren Signed-off-by: Andreas Fenkart Signed-off-by: Ulf Hansson --- drivers/mmc/host/omap_hsmmc.c | 65 +++++++++++++++++-------------------------- 1 file changed, 26 insertions(+), 39 deletions(-) (limited to 'drivers/mmc') diff --git a/drivers/mmc/host/omap_hsmmc.c b/drivers/mmc/host/omap_hsmmc.c index f4f1bcd632f3..82b40b85293f 100644 --- a/drivers/mmc/host/omap_hsmmc.c +++ b/drivers/mmc/host/omap_hsmmc.c @@ -207,7 +207,6 @@ struct omap_hsmmc_host { int use_dma, dma_ch;
