Subject: [PATCH 6/7] eeprom: at24: don't check chip.byte_len for power of two
Date: Thu, 30 Nov 2017 07:49:10 +0100	[thread overview]
Message-ID: <bf82e4d8-66df-0d2e-d6e0-9874dbd763b1@gmail.com> (raw)
In-Reply-To: <c0855fe6-09b4-aed1-774d-5417c78faa8b@gmail.com>

When using AT24_FLAG_SERIAL and AT24_FLAG_MAC we expose just parts of
the chip. These parts can have arbitrary size (e.g. a 6 byte MAC),
so remove the check for power of two.
