iio:inkern: fix overwritten -EPROBE_DEFER in of_iio_channel_get_by_name

2014-10-05T21:54:12+00:00

commit 872687f626e033b4ddfaec1e410057cfc6636d77 upstream.

Fixes: a2c12493ed7e ('iio: of_iio_channel_get_by_name() returns non-null pointers for error legs')

which improperly assumes that of_iio_channel_get_by_name must always
return NULL and thus now hides -EPROBE_DEFER.

commit 9e5846be33277802c0c76e5c12825d0e4d27f639 upstream.

This can result in wrong reference count for trigger device, call
iio_trigger_get to increment reference.

iio: buffer: Fix demux table creation

2014-08-07T21:30:26+00:00

commit 61bd55ce1667809f022be88da77db17add90ea4e upstream.

When creating the demux table we need to iterate over the selected scan mask for
the buffer to get the samples which should be copied to destination buffer.
Right now the code uses the mask which contains all active channels, which means
the demux table contains entries which causes it to copy all the samples from
source to destination buffer one by one without doing any demuxing.

iio: of_iio_channel_get_by_name() returns non-null pointers for error legs

2014-07-09T18:14:02+00:00

commit a2c12493ed7e63a18cef33a71686d12ffcd6600e upstream.

Currently in the inkern.c code for IIO framework, the function
of_iio_channel_get_by_name() will return a non-NULL pointer when
it cannot find a channel using of_iio_channel_get() and when it
tries to search for 'io-channel-ranges' property and fails. This
is incorrect behaviour as the function which calls this expects
a NULL pointer for failure. This patch rectifies the issue.

iio: adc: at91: signedness bug in at91_adc_get_trigger_value_by_name()

commit 4f3bcd878f1d3c730fe00f619b7260c6125d49eb upstream.

at91_adc_get_trigger_value_by_name() was returning -ENOMEM truncated to
a positive u8 and that doesn't work.  I've changed it to int and
refactored it to preserve the error code.
