Subject: [PATCH v3] iio: light: bh1750: Resolve compiler warning and make code more readable
Date: Fri, 13 Sep 2019 22:24:13 +0200
Message-ID: <20190913202413.3034-1-kw@linux.com> (raw)
In-Reply-To: <20190910203814.31075-1-kw@linux.com>

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").

Signed-off-by: Krzysztof Wilczynski <kw@linux.com>

Changes in v3:
  Updated wording of the commit message as per the review feedback.

Changes in v2:
  Made definition of bh1750_chip_info_tbl separate from declaration
  as per the review feedback.  This also makes the code more readable.
  Updated wording of the subject and the commit message.
