rpmsg: qcom_glink_native: fix error return code of qcom_glink_rx_data()

2021-05-19T08:56:23Z

[ Upstream commit 26594c6bbb60c6bc87e3762a86ceece57d164c66 ] When idr_find() returns NULL to intent, no error return code of qcom_glink_rx_data() is assigned. To fix this bug, ret is assigned with -ENOENT in this case.

rpmsg: glink: add include of header file

2021-01-06T04:22:40Z

With an x86_64 architecture W=1 build, qcom_glink_ssr_notify() is reported as having no previous prototype. The prototype is found in "qcom_glink.h", so we just need "qcom_glink_ssr.c" to include that file.

rpmsg: glink: fix some kerneldoc comments

2021-01-06T03:45:06Z

The kerneldoc comments for the do_cleanup_msg and cleanup_done_msg structures describe the fields, but don't prefix the field names with "@". Add those, to get rid of some W=1 build warnings on an x86_64 architecture build.

rpmsg: Turn name service into a stand alone driver

2020-11-24T16:11:59Z

Make the RPMSG name service announcement a stand alone driver so that it can be reused by other subsystems. It is also the first step in making the functionatlity transport independent, i.e that is not tied to virtIO.
