commit dae0b77cb8b2d3c61819de7bde620c58cb48f9c2
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0WL

--------------------------------

[ Upstream commit 8f2b6bc7 ]

The driver does not handle the failure case while calling
dma_set_mask_and_coherent API.

In case of failure, capture the return value of API and then report an
error.

Addresses-coverity: Unchecked return value (CHECKED_RETURN)
