crypto: stm32/cryp - check early input data
[ Upstream commit 39e6e699c7fb92bdb2617b596ca4a4ea35c5d2a7 ]
Some auto tests failed because driver wasn't returning the expected
error with some input size/iv value/tag size.
Now:
Return 0 early for empty buffer. (We don't need to start the engine for
an empty input buffer).
Accept any valid authsize for gcm(aes).
Return -EINVAL if iv for ccm(aes) is invalid.
Return -EINVAL if buffer size is a not a multiple of algorithm block size.
Fixes: 9e054ec21ef8 ("crypto: stm32 - Support for STM32 CRYP crypto module")
