Documentation: HID: hid-sensor editing & corrections
Do basic editing & correction to hid-sensor.rst: - use HID consistently instead of hid - drop a duplicate word - change article adjective an -> a - fix grammar & punctuation - spell out RW -> read-write - hyphenate multi-word adjectives Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Jiri Kosina <jikos@kernel.org> Cc: Jonathan Cameron <jic23@kernel.org> Cc: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Cc: linux-input@vger.kernel.org Cc: linux-iio@vger.kernel.org Cc: Jonathan Corbet <corbet@lwn.net> Cc: linux-doc@vger.kernel.org Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
