To fix:

WARNING: It's generally not useful to have the filename in the file
+ * fs/f2fs/super.c

WARNING: quoted string split across lines
+               f2fs_warn(sbi, "using deprecated layout of large_nat_bitmap, "
+                         "please run fsck v1.13.0 or higher to repair, chksum_offset: %u, "

WARNING: quoted string split across lines
+                         "please run fsck v1.13.0 or higher to repair, chksum_offset: %u, "
+                         "fixed with patch: \"f2fs-tools: relocate chksum_offset for large_nat_bitmap feature\"",

WARNING: quoted string split across lines
+                                "can't mount with superblock charset: %s-%u.%u.%u "

+                                       f2fs_err(sbi, "Need to recover fsync data, but "
+                                               "write access unavailable, please try "

WARNING: printk() should include KERN_<LEVEL> facility level
+               printk("F2FS not supported on PAGE_SIZE(%lu) != %d\n",
