Hello all,
Since version next-20230613[1], we have observed build failures in the linux-next tree [2]
We have bisected the issue to the following patch[3].
commit ef104443bffa004f631729dfc924f0b84abbd602
Author: Arnd Bergmann arnd@xxxxxxxx

procfs: consolidate arch_report_meminfo declaration
The arch_report_meminfo() function is provided by four architectures,
with a __weak fallback in procfs itself. On architectures that don't
have a custom version, the __weak version causes a warning because
of the missing prototype.
Remove the architecture specific prototypes and instead add one
in linux/proc_fs.h.

Adding the declaration struct seq_file in intel_display_power.h or to explicitly add the header file seq_file.h to the file helps in solving the issue.
Suggestions are welcome.
