2019-09-15iio: light: bh1750: Resolve compiler warning and make code more readableKrzysztof Wilczynski
Separate the declaration of struct bh1750_chip_info from definition of bh1750_chip_info_tbl[] in a single statement as it makes the code hard to read, and with the extra newline it makes it look as if the bh1750_chip_info_tbl[] had no explicit type. This change also resolves the following compiler warning about the unusual position of the static keyword that can be seen when building with warnings enabled (W=1): drivers/iio/light/bh1750.c:64:1: warning: ‘static’ is not at beginning of declaration [-Wold-style-declaration] Related to commit 3a11fbb037a1 ("iio: light: add support for ROHM BH1710/BH1715/BH1721/BH1750/BH1751 ambient light sensors").

2018-09-08iio: light: bh1750: simplify setting PM opsTomasz Duszynski
Relying on CONFIG_PM_SLEEP to set PM ops is not necessary since core will handle everything internally. One have to only make sure that functions that can go unused are marked with __maybe_unused.

2017-08-22iio:light: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron
The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2017-04-01iio: light: bh1750: constify attribute_group structuressimran singhal
Check for attribute_group structures that are only stored in the attrs filed of iio_info structure. As the attrs field of iio_info structures is constant, so these attribute_group structures can also be declared constant.
