ubifs: fix function pointer cast warnings
ubifs has a number of callback functions for ubifs_lpt_scan_nolock() using two different prototypes, either passing a struct scan_data or a struct ubifs_lp_stats, but the caller expects a void pointer instead. clang-16 now warns about this: fs/ubifs/find.c:170:9: error: cast from 'int (*)(struct ubifs_info *, const struct ubifs_lprops *, int, struct scan_data *)' to 'ubifs_lpt_scan_callback' (aka 'int (*)(struct ubifs_info *, const struct ubifs_lprops *, int, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict] 170 | (ubifs_lpt_scan_callback)scan_for_dirty_cb, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ fs/ubifs/find.c:449:9: error: cast from 'int (*)(struct ubifs_info *, const struct ubifs_lprops *, int, struct scan_data *)' to 'ubifs_lpt_scan_callback' (aka 'int (*)(struct ubifs_info *, const struct ubifs_lprops *, int, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict] 449 | (ubifs_lpt_scan_callback)scan_for_free_cb, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Change all of these callback functions to actually take the void * argument that is passed by their caller.
