And unlike the other helpers we don't require a <asm/dma-direct.h> as this helper is a special case for ia64 only, and this keeps it as simple as possible. Signed-off-by: NChristoph Hellwig <hch@lst.de>

phys_to_dma, dma_to_phys and dma_capable are helpers published by architecture code for use of swiotlb and xen-swiotlb only. Drivers are not supposed to use these directly, but use the DMA API instead. Move these to a new asm/dma-direct.h helper, included by a linux/dma-direct.h wrapper that provides the default linear mapping unless the architecture wants to override it. In the MIPS case the existing dma-coherent.h is reused for now as untangling it will take a bit of work. Signed-off-by: NChristoph Hellwig <hch@lst.de> Acked-by: NRobin Murphy <robin.murphy@arm.com>

Commit 2b83ff96 ("led: core: Fix brightness setting when setting delay_off=0") replaced del_timer_sync(&led_cdev->blink_timer) with led_stop_software_blink() in led_blink_set(), which additionally clears LED_BLINK_SW flag as well as zeroes blink_delay_on and blink_delay_off properties of the struct led_classdev. Cleansing of the latter ones wasn't required to fix the original issue but wasn't considered harmful. It nonetheless turned out to be so in case when pointer to one or both props is passed to led_blink_set() like in the ledtrig-timer.c. In such cases zeroes are passed later in delay_on and/or delay_off arguments to led_blink_setup(), which results either in stopping the software blinking or setting blinking frequency always to 1Hz. Avoid using led_stop_software_blink() and add a single call required to clear LED_BLINK_SW flag, which was the only needed modification to fix the original issue.

In the current driver, OOB bytes are accessed in raw mode, and when a page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the driver must read the whole spare area (64 bytes in case of a 2k page, 16 bytes for a 512 page). The driver was only reading the free OOB bytes, which was leaving some unread data in the FIFO and was somehow leading to a timeout. We could patch the driver to read ->spare_size + ->ecc_size instead of just ->spare_size when READOOB is requested, but we'd better make in-band and OOB accesses consistent. Since the driver is always accessing in-band data in non-raw mode (with the ECC engine enabled), we should also access OOB data in this mode. That's particularly useful when using the BCH engine because in this mode the free OOB bytes are also ECC protected.
