The kbuild bot reported the following compiler errors when compiling on
MIPS with CONFIG_QCOM_OCMEM disabled:
In file included from <command-line>:0:0:
>> include/soc/qcom/ocmem.h:43:49: warning: 'struct device' declared
inside parameter list will not be visible outside of this
definition or declaration
static inline struct ocmem *of_get_ocmem(struct device *dev)
^~~~~~
include/soc/qcom/ocmem.h: In function 'of_get_ocmem':
>> include/soc/qcom/ocmem.h:45:9: error: implicit declaration of
function 'ERR_PTR' [-Werror=implicit-function-declaration]
return ERR_PTR(-ENODEV);
^~~~~~~
>> include/soc/qcom/ocmem.h:45:18: error: 'ENODEV' undeclared (first
use in this function)
return ERR_PTR(-ENODEV);
Add the proper includes to fix the compiler errors.
