Subject: [PATCH] ax88796: export ax_NS8390_init() hook
Git-commit: 375df5f8c1812c59930cfed14ff4cc15929c8f2f
Patch-mainline: v5.15-rc1
References: git-fixes

The block I/O code for the new X-Surf 100 ax88796 driver needs
ax_NS8390_init() for error fixup in its block_output function.

Export this static function through the ax_NS8390_reinit()
wrapper so we can lose the lib8380.c include in the X-Surf 100
driver.

[arnd: add the declaration in the header to avoid a -Wmissing-prototypes warning]
Fixes: 861928f4e60e826c ("net-next: New ax88796 platform
driver for Amiga X-Surf 100 Zorro board (m68k)")
