We keep the argument as mmc_host, though, because the callback is used very early when mmc_card is not yet populated. Signed-off-by: Wolfram Sang --- Ulf: I really think the callback rename makes sense here to make it obvious for driver authors that the card should be reset. Because we got it wrong and at least bcm2835 has it also wrong, maybe meson as well. drivers/mmc/core/core.c | 4 ++-- drivers/mmc/core/mmc.c | 4 ++-- drivers/mmc/host/bcm2835.c | 2 +- drivers/mmc/host/dw_mmc.c | 2 +- drivers/mmc/host/meson-mx-sdhc-mmc.c | 2 +- drivers/mmc/host/mtk-sd.c | 2 +- drivers/mmc/host/sdhci.c | 2 +- drivers/mmc/host/sunxi-mmc.c | 2 +- drivers/mmc/host/uniphier-sd.c | 2 +- include/linux/mmc/host.h | 2 +- 10 files changed, 12 insertions(+), 12 deletions(-) diff --git a/drivers/mmc/core/core.c b/drivers/mmc/core/core.c index 57c64c0583ac..8cc2b746414b 100644 --- a/drivers/mmc/core/core.c +++ b/drivers/mmc/core/core.c @@ -1991,9 +1991,9 @@ static void mmc_hw_reset_for_init(struct mmc_host *host) { mmc_pwrseq_reset(host);
