Looks like <linux/device.h> or <linux/dynamic_debug.h> is missing.

$ egrep -w '__dynamic_pr_debug|DEFINE_DYNAMIC_DEBUG_METADATA' -nr linux/include/
linux/include/linux/device.h:1118:
DEFINE_DYNAMIC_DEBUG_METADATA(descriptor, fmt);                 \
linux/include/linux/device.h:1121:
__dynamic_pr_debug(&descriptor, pr_fmt(fmt),            \
linux/include/linux/dynamic_debug.h:45:int __dynamic_pr_debug(struct
_ddebug *descriptor, const char *fmt, ...);
linux/include/linux/dynamic_debug.h:63:#define
DEFINE_DYNAMIC_DEBUG_METADATA(name, fmt)         \
linux/include/linux/dynamic_debug.h:76:
DEFINE_DYNAMIC_DEBUG_METADATA(descriptor, fmt);         \
linux/include/linux/dynamic_debug.h:78:
__dynamic_pr_debug(&descriptor, pr_fmt(fmt),    \
linux/include/linux/dynamic_debug.h:84:
DEFINE_DYNAMIC_DEBUG_METADATA(descriptor, fmt);         \
linux/include/linux/dynamic_debug.h:92:
DEFINE_DYNAMIC_DEBUG_METADATA(descriptor, fmt);         \
linux/include/linux/dynamic_debug.h:101:
DEFINE_DYNAMIC_DEBUG_METADATA(descriptor,               \

Can't say which one is preferred here.
