[U-Boot] [PATCH v3 1/5] sf: Get spi locally from spi_flash

[U-Boot] [PATCH v3 1/5] sf: Get spi locally from spi_flash

[Jagan Teki]

For better code readabilty, get the spi pointer from
spi_flash{} locally and use it instead of direct
dereferring spi pinter as flash->spi->*

[U-Boot] [PATCH v3 2/5] spi: make mode visible to both dm and non-dm

[Jagan Teki]

Couldn't find the exact reason to define 'mode' for dm,
probably it is not using in non-dm drivers but it need
to visible both dm and non-dm as mode data is getting
dereferred in spi flash core ie common to both.
