2017-02-09staging: fsl-mc: remove slab cache for mc devicesLaurentiu Tudor
Let's drop the slab cache for objects until we actually have proof that it improves performance. This makes the code cleaner. Signed-off-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> Acked-by: Stuart Yoder <stuart.yoder@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-02-09staging: fsl-mc: don't use devres api for refcounted objectsLaurentiu Tudor
Mixing two memory management systems, in this case managed device resource api and refcounted objects is a bad idea. Lifetime of an object is controlled by its refcount so allocating it with other apis that have their own lifetime control is not ok. Drop devm_*() apis in favor of plain allocations.

2017-02-09staging: fsl-mc: add device release callbackLaurentiu Tudor
When hot unplugging a mc-bus device the kernel displays this pertinent message, followed by a stack dump: "Device 'foo.N' does not have a release() function, it is broken and must be fixed." Add the required callback to fix and drop the now uneeded explicit freeing.

2017-02-09staging: gdm724x: fix a couple array overflowsDan Carpenter
The find_dev_index() function is frustrating. If you give it an invalid index then it returns 0. That was the intent except there is an off-by-one so it can return MAX_NIC_TYPE which is one higher than we want. There is one caller which had a sanity check to catch invalid returns, but the other two callers assumed that index was valid. My feeling is that when we are given invalid indexes, that should be treated like an error and we abandon what we were doing.

Stop execution if CMD_T_STOP has been set for a command just after the command has been added to the device command list and before .write_pending() is called. The following sequence can trigger this: - transport_handle_cdb_direct() gets called.
