2015-09-29staging: comedi: comedidev.h: tweak kernel-doc for struct comedi_asyncIan Abbott1-7/+12
Tweak the formatting of the kernel-doc formatted comment for `struct comedi_async` in order to stop it generating bogus headings for text before a colon.

2015-09-29staging: comedi: comedidev.h: use enum for COMEDI_CB_... constantsIan Abbott1-11/+12
The existing constants `COMEDI_CB_EOS` etc. are in the form of macros and have a bogus kernel-doc comment. Change them to `enum` constants so they can be documented properly with kernel-doc.

2015-09-29staging: most: add poll syscall to AIM cdevChristian Gromm3-0/+43
This patch adds the implementation of the poll syscall to the AIM cdev.

2015-09-29staging: most: add fair buffer distributionChristian Gromm6-7/+36
This patch ensures a fair distribution of buffers, when two AIMs share a single channel. The AIMs then won't be able to use more than half of all pre-allocated buffers of the linked channel. However, in case the channel is not shared, the AIM can exclusively use all available buffers.

2015-09-29staging: most: fix race condition in AIM networkingChristian Gromm1-0/+3
If the network device is being opened right after it has been registered via function register_netdev(), the device state is not yet consistent in the context of function ndo_open().

2015-09-29staging: most: remove aim resetChristian Gromm1-5/+0
This patch partly reverts a modification of function most_stop_channel() that is trying to reset an established link between an AIM and an HDM in all suitable places.
