[PATCH 5.4 239/408] mtd: spinand: gigadevice: Only one dummy byte in QUADIO

[Greg Kroah-Hartman]

From: Hauke Mehrtens <hauke@xxxxxxxxxx>

[ Upstream commit 6387ad9caf8f09747a8569e5876086b72ee9382c ]

The datasheet only lists one dummy byte in the 0xEH operation for the
following chips:
* GD5F1GQ4xExxG
* GD5F1GQ4xFxxG
* GD5F1GQ4UAYIG
* GD5F4GQ4UAYIG
