![]() This change adds a parameter to the {devm_}iio_triggered_buffer_setup() functions to assign the extra sysfs buffer attributes that are typically assigned via iio_buffer_set_attrs(). The functions also get renamed to iio_triggered_buffer_setup_ext() & devm_iio_triggered_buffer_setup_ext(). For backwards compatibility the old {devm_}iio_triggered_buffer_setup() functions are now macros wrap the new (renamed) functions with NULL for the buffer attrs. The aim is to remove iio_buffer_set_attrs(), so in the iio_triggered_buffer_setup_ext() function the attributes are assigned directly to 'buffer->attrs'. When adding multiple IIO buffers per IIO device, it can be pretty cumbersome to first allocate a set of buffers, then to dig them out of IIO to assign extra attributes (with iio_buffer_set_attrs()). Naturally, the best way would be to provide them at allocation time, which is what this change does. At this moment, buffers allocated with {devm_}iio_triggered_buffer_setup() are the only ones in mainline IIO to call iio_buffer_set_attrs().
