There is a bug in the conversion code: if nbd_send_cmd() returns BLK_STS_RESOURCE, nbd_queue_rq() should return BLK_STS_RESOURCE instead of BLK_STS_OK. Fix this, move the conversion code into nbd_handle_cmd() and fix the remaining sparse warnings. This patch fixes the following sparse warnings: drivers/block/nbd.c:673:32: warning: incorrect type in return expression (different base types) drivers/block/nbd.c:673:32: expected int drivers/block/nbd.c:673:32: got restricted blk_status_t [usertype] drivers/block/nbd.c:714:48: warning: incorrect type in return expression (different base types) drivers/block/nbd.c:714:48: expected int drivers/block/nbd.c:714:48: got restricted blk_status_t [usertype] drivers/block/nbd.c:1120:21: warning: incorrect type in assignment (different base types) drivers/block/nbd.c:1120:21: expected int [assigned] ret drivers/block/nbd.c:1120:21: got restricted blk_status_t [usertype] drivers/block/nbd.c:1125:16: warning: incorrect type in return expression (different base types) drivers/block/nbd.c:1125:16: expected restricted blk_status_t drivers/block/nbd.c:1125:16: got int [assigned] ret Cc: Christoph Hellwig <hch(a)lst.de> Cc: Josef Bacik <jbacik(a)fb.com> Cc: Yu Kuai <yukuai3(a)huawei.com> Cc: Markus Pargmann <mpa(a)pengutronix.de> Fixes: fc17b6534eb8 ("blk-mq: switch ->queue_rq return value to blk_status_t") Cc: stable(a)vger.kernel.org Signed-off-by: Bart Van Assche <bvanassche(a)acm.org> Link: https://lore.kernel.org/r/20240510202313.25209-6-bvanassche@acm.org Signed-off-by: Jens Axboe <axboe(a)kernel.dk> diff --git a/drivers/block/nbd.c b/drivers/block/nbd.c index 29e43ab1650c..22a79a62cc4e 100644 --- a/drivers/block/nbd.c +++ b/drivers/block/nbd.c @@ -588,6 +588,10 @@ static inline int was_interrupted(int result) return result == -ERESTARTSYS || result == -EINTR; } +/* + * Returns BLK_STS_RESOURCE if the caller should retry after a delay.

[PATCH 2/3] spi: stm32: qspi: Clamp stm32_qspi_get_mode() output to CCR_BUSWIDTH_4

by patrice.chotard＠foss.st.com

From: Patrice Chotard <patrice.chotard(a)foss.st.com> In case usage of OCTAL mode, buswidth parameter can take the value 8. As return value of stm32_qspi_get_mode() is used to configure fields of CCR registers that are 2 bits only (fields IMODE, ADMODE, ADSIZE, DMODE), clamp return value of stm32_qspi_get_mode() to 4.

[PATCH 1/3] spi: stm32: qspi: Fix dual flash mode sanity test in stm32_qspi_setup()

by patrice.chotard＠foss.st.com

From: Patrice Chotard <patrice.chotard(a)foss.st.com> Misplaced parenthesis make test of mode wrong in case mode is equal to SPI_TX_OCTAL or SPI_RX_OCTAL. Simplify this sanity test, if one of this bit is set, property cs-gpio must be present in DT.
