The other two patches are needed to enhance the driver's visibility for ST platforms. This patchset version 3 addresses the issues identified by Herbert. The code that raised a warning was in fact useless as there is already an overflow check in the "stm32_cryp_dma_check" function so I removed it. I've also added a new patch that correct a spinlock recursion warning. Maxime Méré (4): crypto: stm32/cryp - use dma when possible. crypto: stm32/cryp - increase priority crypto: stm32/cryp - add CRYPTO_ALG_KERN_DRIVER_ONLY flag crypto: stm32/cryp - call finalize with bh disabled drivers/crypto/stm32/stm32-cryp.c | 719 ++++++++++++++++++++++++++++-- 1 file changed, 674 insertions(+), 45 deletions(-)
