stable inclusion from stable-v5.10.122 commit 6b7cf2212223b5128f68358e7b22b5de89ae2ec1 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5W6OE
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit b92ffb1eddd9a66a90defc556dcbf65a43c196c7 ]
The function rio_karam_init() should return -ENOMEM instead of value 0 (USB_STOR_TRANSPORT_GOOD) when allocation fails.
Similarly, it should return -EIO when rio_karma_send_command() fails.
