hsi: correctly handle return value of kzalloc

2015-10-19T09:42:02+00:00

Since kzalloc can be failed in memory pressure,
its return value should be checked and handled.

hsi: fix double kfree

2015-10-14T11:22:00+00:00

When device_register() fails, kfree() is called in hsi_client_release(),
hence there is no need to call kfree in err3 again.

HSI: export method to (un)register clients

2014-05-15T22:54:41+00:00

Expose method for registering and unregistering HSI clients, so that
client drivers can register other client drivers.

This is useful for HSI drivers, which want to use the functionality
of other HSI drivers. For example the N900 modem driver can load HSI
drivers for mcsaab protocol and speech protocol.

hsi: convert bus code to use dev_groups

2013-10-17T01:36:04+00:00

The dev_attrs field of struct bus_type is going away soon, dev_groups
should be used instead.  This converts the hsi code to use the
correct field.

drivers: avoid format string in dev_set_name

2013-07-03T23:07:41+00:00

Calling dev_set_name with a single paramter causes it to be handled as a
format string.  Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents,
including wrappers like device_create*() and bdi_register().

Don't document "private:" fields with kernel-doc notation.
If you want to leave them fully documented, that's OK, but
then don't mark them as "private:".

HSI: hsi: Rework hsi_event interface

2012-04-23T11:23:32+00:00

Remove custom hack and make use of the notifier chain interfaces for
delivering events from the ports to their associated clients.
Clients that want to receive port events need to register their callbacks
using hsi_register_port_event(). The callbacks can be called in interrupt
context. Use hsi_unregestier_port_event() to undo the registration.
