mei: bus: use simple sprintf for sysfs

2020-01-10T12:20:49Z

Replace scnprintf with simple sprintf for sysfs files. it is implicitly known that the buffer is big enough for the variables to fit in. Signed-off-by: Tomas Winkler Link: https://lore.kernel.org/r/20191126123002.4835-1-tomas.winkler@intel.com Signed-off-by: Greg Kroah-Hartman

mei: bus: add more client attributes to sysfs

2019-11-16T11:58:54Z

Export more client attributes via sysfs that are usually obtained upon connection. In some cases, for example a monitoring application may wish to know the attributes without actually performing the connection. Added attributes: max number of connections, fixed address, max message length.

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

2019-11-05T17:19:01Z

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

2019-02-26T10:53:56Z

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.

mei: bus: need to unlink client before freeing

2018-09-12T07:14:24Z

In case a client fails to connect in mei_cldev_enable(), the caller won't call the mei_cldev_disable leaving the client in a linked stated. Upon driver unload the client structure will be freed in mei_cl_bus_dev_release(), leaving a stale pointer on a fail_list. This will eventually end up in crash during power down flow in mei_cl_set_disonnected().

In case the device is not connected it doesn't 'get' hw module and hence should not 'put' it on disable.
