mei: bus: prefix device names on bus with the bus name

2019-12-05T08:21:26+00:00

commit 7a2b9e6ec84588b0be65cc0ae45a65bac431496b upstream. Add parent device name to the name of devices on bus to avoid device names collisions for same client UUID available from different MEI heads. Namely this prevents sysfs collision under /sys/bus/mei/device/ In the device part leave just UUID other parameters that are required for device matching are not required here and are just bloating the name.

mei: avoid FW version request on Ibex Peak and earlier

2019-10-17T20:45:10+00:00

commit f8204f0ddd62966a0e79c2804963a21e3540dd82 upstream. The fixed MKHI client on PCH 6 gen platforms does not support fw version retrieval. The error is not fatal, but it fills up the kernel logs and slows down the driver start. This patch disables requesting FW version on GEN6 and earlier platforms.

mei: bus: move hw module get/put to probe/release

2019-03-23T19:09:39+00:00

commit b5958faa34e2f99f3475ad89c52d98dfea079d33 upstream. Fix unbalanced module reference counting during internal reset, which prevents the drivers unloading. Tracking mei_me/txe modules on mei client bus via mei_cldev_enable/disable is error prone due to possible internal reset flow, where clients are disconnected underneath. Moving reference counting to probe and release of mei bus client driver solves this issue in simplest way, as each client provides only a single connection to a client bus driver.
