Subject: [PATCH] misc: apds9802als: fix signedness bug
Date: Thu, 28 Oct 2010 15:13:58 +0400 [thread overview]
Message-ID: <1288264438-10578-1-git-send-email-segooon@gmail.com> (raw)
i2c_smbus_read_byte_data() may return negative error code. This is not
seen to als_sensing_range_store() as the result is stored in unsigned int.
Made it signed.
