Subject: spi: sh-msiof: Remove sh_msiof_spi_priv.chipdata
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a6802cc05f9e48e86bc3f9f056c74a69dc5e37fa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

spi: sh-msiof: Remove sh_msiof_spi_priv.chipdata

After probe time, the pointer to the sh_msiof_chipdata structure in the
sh_msiof_spi_priv structure is used only for checking the SPI master flags.
As these are also available in the spi_master structure, convert the
users to access those, and remove the pointer.
