Subject: [PATCH v2 2/8] staging:iio:ade7854: Fix the wrong number of bits to read
Date: Fri, 16 Mar 2018 19:48:51 -0300 [thread overview]
Message-ID: <b5f76bfcf37667a473ec962bfafadc7f9455bec6.1521239766.git.rodrigosiqueiramelo@gmail.com> (raw)
In-Reply-To: <cover.1521239766.git.rodrigosiqueiramelo@gmail.com>
The function ade7854_i2c_read_reg_32() have to invoke the
i2c_master_recv() for read 32 bits values, however, the counter is set
to 3 which means 24 bits. This patch fixes the wrong size of 24 bits, to
32 bits. Finally, this patch is based on John Syne patches.
