Subject: [PATCH 7/7] mtd: spi-nor: remove unneeded smpt zeroization
Date: Thu, 8 Nov 2018 11:07:21 +0000	[thread overview]
Message-ID: <20181108110653.21063-8-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20181108110653.21063-1-tudor.ambarus@microchip.com>

The entire smpt array is initialized with data read from sfdp,
there is no need to init it with zeroes before.
