The omapdrm dss driver currently fails to build in some configurations when the pinctrl and seq_print declarations are not visible:
omapdrm/dss/dss.c:1268:2: error: implicit declaration of function 'pinctrl_pm_select_sleep_state' [-Werror=implicit-function-declaration] omapdrm/dss/dss.c:1277:2: error: implicit declaration of function 'pinctrl_pm_select_default_state' [-Werror=implicit-function-declaration] omapdrm/dss/hdmi_wp.c:26:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration] omapdrm/dss/hdmi_pll.c:30:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration] omapdrm/dss/hdmi_phy.c:34:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
This adds the appropriate include statements.
Signed-off-by: Arnd Bergmann arnd@arndb.de Fixes: 9960aa7cb58c ("drm/omap: move omapdss & displays under omapdrm") --- Found on ARM randconfig builds. I assume there are also configurations in which this is not needed because the headers get included through other headers, and I have not investigated exactly what options cause this as the fix seems obvious and harmless.
