The driver need use mutex to avoid concurrency, > so we can't use tasklet here, the patch need to be removed. > > The spinlock host->lock and pcr->lock may deadlock, one way to solve the > deadlock is remove host->lock in sd_isr_done_transfer(), but if using > workqueue the we can avoid using the spinlock and also avoid the problem. > > Signed-off-by: Micky Ching <micky_ching@xxxxxxxxxxxxxx> > --- > drivers/mfd/rtsx_pcr.c | 132 ++++-------- > drivers/mmc/host/rtsx_pci_sdmmc.c | 418 ++++++------------------------------- > include/linux/mfd/rtsx_common.h | 1 - > include/linux/mfd/rtsx_pci.h | 6 - > 4 files changed, 109 insertions(+), 448 deletions(-) This patch should be sent to the -rcs as soon as possible: Acked-by: Lee Jones <lee.jones@xxxxxxxxxx> -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
