[PATCH v2 0/3] fs: fat: avoid invalid filenames

The FAT32 File System Specification requires leading and trailing spaces as well as trailing periods of long names to be ignored.

Up to now U-Boot could create files with invalid file names violating the restriction above.

With the patches this is avoided.

v2: Change the separation of duties between split_filename() and normalize_longname(): split_filename() may return '.' and '..'.

Heinrich Schuchardt (3): fs: fat: usage basename in file_fat_write_at, fat_mkdir fs: fat: must not write directory '.' and '..' fs: fat: remove trailing periods from long name
