Subject: mei: pxp: fix mei_pxp_send_message return value
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=be6f9a39969a4ad01f0051a9b94af6e7f4d2d7ac;p=linux.git

mei: pxp: fix mei_pxp_send_message return value

mei_pxp_send_message() should return zero on success and
cannot propagate number of bytes as returned by internally
called mei_cldev_send().

Fixes: ee5cb39348e6 ("mei: pxp: recover from recv fail under memory pressure")
