[PATCH v2 1/2] regmap: include <linux/ktime.h> from include/linux/regmap.h

[sean.wang]

From: Sean Wang <sean.wang@xxxxxxxxxxxx>

Similar to the readx_poll_timeout() macro calling ktime_* and using
ktime_t type, which is declared in <linux/ktime.h>. So, make
include/linux/regmap.h explicitly include <linux/ktime.h>, like
include/linux/iopoll.h does.  Otherwise, users of the macro will see
below errors.

error: implicit declaration of function âktime_add_usâ
[-Werror=implicit-function-declaration]

error: implicit declaration of function âktime_getâ
[-Werror=implicit-function-declaration]

error: implicit declaration of function âktime_compareâ
[-Werror=implicit-function-declaration]

include/linux/regmap.h:128:2: error: unknown type name âktime_tâ
  ktime_t __timeout = ktime_add_us(ktime_get(), __timeout_us); \
