Subject: [PATCH] accel/qaic: mark debugfs stub functions as static inline

From: Arnd Bergmann <arnd@...db.de>

The alternative stub functions are listed as global, which produces
a build failure in some configs:

In file included from drivers/accel/qaic/qaic_drv.c:31:
drivers/accel/qaic/qaic_debugfs.h:16:5: error: no previous prototype for 'qaic_bootlog_register' [-Werror=missing-prototypes]
   16 | int qaic_bootlog_register(void) { return 0; }
      |     ^~~~~~~~~~~~~~~~~~~~~

      |      ^~~~~~~~~~~~~~~~~

Make them static inline as intended.
