crypto: hisilicon/qm - disable same error report before resetting
If an error indicating that the device needs to be reset is reported, disable the error reporting before device reset is complete, enable the error reporting after the reset is complete to prevent the same error from being reported repeatedly. Fixes: eaebf4c ("crypto: hisilicon - Unify hardware error init/uninit into QM") Signed-off-by: Weili Qian <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
