2020-04-24crypto: chelsio - remove redundant assignment to variable errorColin Ian King1-1/+1
The variable error is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

2020-04-16crypto: ccp -- don't "select" CONFIG_DMADEVICESArnd Bergmann1-2/+1
DMADEVICES is the top-level option for the slave DMA subsystem, and should not be selected by device drivers, as this can cause circular dependencies such as: drivers/net/ethernet/freescale/Kconfig:6:error: recursive dependency detected! drivers/net/ethernet/freescale/Kconfig:6: symbol NET_VENDOR_FREESCALE depends on PPC_BESTCOMM drivers/dma/bestcomm/Kconfig:6: symbol PPC_BESTCOMM depends on DMADEVICES drivers/dma/Kconfig:6: symbol DMADEVICES is selected by CRYPTO_DEV_SP_CCP drivers/crypto/ccp/Kconfig:10: symbol CRYPTO_DEV_SP_CCP depends on CRYPTO crypto/Kconfig:16: symbol CRYPTO is selected by LIBCRC32C lib/Kconfig:222: symbol LIBCRC32C is selected by LIQUIDIO drivers/net/ethernet/cavium/Kconfig:65: symbol LIQUIDIO depends on PTP_1588_CLOCK drivers/ptp/Kconfig:8: symbol PTP_1588_CLOCK is implied by FEC drivers/net/ethernet/freescale/Kconfig:23: symbol FEC depends on NET_VENDOR_FREESCALE The LIQUIDIO driver causing this problem is addressed in a separate patch, but this change is needed to prevent it from happening again. Using "depends on DMADEVICES" is what we do for all other implementations of slave DMA controllers as well.

2020-04-10mm/vma: introduce VM_ACCESS_FLAGSAnshuman Khandual1-1/+1
There are many places where all basic VMA access flags (read, write, exec) are initialized or checked against as a group. One such example is during page fault. Existing vma_is_accessible() wrapper already creates the notion of VMA accessibility as a group access permissions. Hence lets just create VM_ACCESS_FLAGS (VM_READ|VM_WRITE|VM_EXEC) which will not only reduce code duplication but also extend the VMA accessibility concept in general.
