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@arndb.de

    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.

The issue is particularly because of this change within the patch.

Suggestions are welcome.

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.
