6.11-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.
Fixes: eff9604390d6 ("mtd: spi-nor: spansion: add octal DTR support in RD_ANY_REG_OP")
