Subject: [PATCH] mtd: m25p80: Use OPCODE_QUAD_READ_4B for 4-byte addressing
Date: Wed, 15 Jan 2014 16:48:55 +0100	[thread overview]
Message-ID: <1389800935-6468-1-git-send-email-geert@linux-m68k.org> (raw)

From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>

commit 3487a63955c34ea508bcf4ca5131ddd953876e2d ("drivers: mtd: m25p80: add
quad read support") in -next added both the 3-byte OPCODE_QUAD_READ and the
4-byte OPCODE_QUAD_READ_4B, but incorrectly uses OPCODE_QUAD_READ for both
3-byte and 4-byte addressing.

Use OPCODE_QUAD_READ_4B in the 4-byte case to fix this.
