6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Takahiro Kuwano <Takahiro.Kuwano@xxxxxxxxxxxx> [ Upstream commit b61c35e3404557779ec427c077f7a9f057bb053d ] In octal DTR mode, RD_ANY_REG_OP needs to use 4-byte address regardless of flash's internal address mode. Use nor->addr_nbytes which is set to 4 during setup.
