[PATCH] modpost: Add line break in the section mismatch warning

[Tiezhu Yang]

The section mismatch warning may be too long, add an line break in it.

Without this patch:

  LD      vmlinux.o
  MODPOST vmlinux.symvers
WARNING: modpost: vmlinux.o(___ksymtab+prom_init_numa_memory+0x0): Section mismatch in reference from the variable __ksymtab_prom_init_numa_memory to the function .init.text:prom_init_numa_memory()
The symbol prom_init_numa_memory is exported and annotated __init
Fix this by removing the __init annotation of prom_init_numa_memory or drop the export.

With this patch:

  LD      vmlinux.o
  MODPOST vmlinux.symvers
WARNING: modpost: vmlinux.o(___ksymtab+prom_init_numa_memory+0x0): Section mismatch in reference
from the variable __ksymtab_prom_init_numa_memory to the function .init.text:prom_init_numa_memory()
The symbol prom_init_numa_memory is exported and annotated __init
Fix this by removing the __init annotation of prom_init_numa_memory or drop the export.

This is based on Linux 5.19-rc4.
