staging: greybus: fix up SPDX comment in .h files When these files originally got an SPDX tag, I used // instead of /* */ for the .h files. Fix this up to use // properly.

greybus: start improving manifest parsing Currently the module manifest parsing code is sort of representative only and is not really very useful. This patch begins doing "real" parsing of the module manifest. It scans the module manifest to identify the descriptors it holds. It then verifies there's only one module descriptor found, and initializes new some fields in the gb_module structure based on what it contains (converting what's found to native byte order). Note that if anything unexpected is found or other errors occur when parsing the manifest, the parse fails. Because we now save this converted information when it's parsed we no longer have a greybus_descriptor_module struct within a struct gb_module. And because we've already converted these values, we can do a little less work displaying values in sysfs. (We also now show vendor, product, and version values in the right byte order.) This eliminates the need for greybus_string(), so get rid of it. It also slightly simplifies the greybus module matching code. Move some existing parsing code into a new file, "manifest.c".

greybus: manifest: Use interface descriptor instead of module descriptor to get information A module can have more than one interfaces and we get hotplug events or manifests for interfaces, not modules. Details like version, vendor, product id, etc. can be different for different interfaces within the same module and so shall be fetched from interface descriptor instead of module descriptor. So what we have been doing for module descriptors until now must be done for interface descriptors. There can only be one interface descriptor in the manifest. Module descriptor isn't used anymore and probably most of its fields can be removed now. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>

staging: greybus: add missing includes Before moving greybus core out of staging and moving header files to include/linux some greybus header files were missing the necessary includes.
