drm/panel: make DRM_PANEL_LD9040 depend on SPI
Rather than DRM_PANEL_LD9040 selecting SPI, which then results in an increase in the probability of Kconf reporting circular dependencies (we're one "select" away from that right now), make this depend on SPI instead. This is akin to having some driver select DRM. Having some drivers depend on a subsystem, and other drivers select a subsystem is a recipe for circular dependencies, and there's really no need for it. The potential circular dependency (which can be caused today by the addition of selecting DRM_PANEL from DRM_IMX_LDB) is: symbol DMADEVICES is selected by SAMSUNG_DMADEV symbol SAMSUNG_DMADEV is selected by S3C64XX_PL080 symbol S3C64XX_PL080 is selected by SPI_S3C64XX symbol SPI_S3C64XX depends on SPI symbol SPI is selected by DRM_PANEL_LD9040 symbol DRM_PANEL_LD9040 depends on DRM_PANEL symbol DRM_PANEL is selected by DRM_IMX_LDB symbol DRM_IMX_LDB depends on MFD_SYSCON symbol MFD_SYSCON is selected by POWER_RESET_KEYSTONE symbol POWER_RESET_KEYSTONE depends on POWER_SUPPLY symbol POWER_SUPPLY is selected by HID_SONY symbol HID_SONY depends on NEW_LEDS symbol NEW_LEDS is selected by BACKLIGHT_ADP8860 symbol BACKLIGHT_ADP8860 depends on BACKLIGHT_CLASS_DEVICE symbol BACKLIGHT_CLASS_DEVICE is selected by FB_MX3 symbol FB_MX3 depends on MX3_IPU symbol MX3_IPU depends on DMADEVICES Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Thierry Reding <treding@nvidia.com>
