Subject: [PATCH v2 1/2] Staging: iio/accel: Changed data type of mask in store_measurement_mode() to u8
Date: Fri,  2 Dec 2011 17:56:55 +0100	[thread overview]
Message-ID: <1322845015-22467-1-git-send-email-rupran@einserver.de> (raw)
In-Reply-To: <20111202164423.GA14982@mail.gnudd.com>

In sca3000_store_measurement_mode() we parse a value from a string
buffer via kstrtou8, and store the parsed value into a u8 after
and-ing it with mask.

As we are only interested in the lowest two bits here and mask is
initialized with a fixed value 0x03, mask may as well be a u8.

[v2]: Fixed a confusing typo in the description (bytes/bits)
