[PATCH v4] drivers/staging/exfat/exfat_super.c: Clean up ffsCamelCase function names

From: Julian Preis
Date: Tue Jan 07 2020 - 09:33:49 EST

Rename every instance of <ffsCamelCaseExample> to <ffs_camel_case_example>
in file exfat_super.c. Fix resulting overlong lines.

Changes in v4:
- Resolve name conflicts for functions create_file, move_file, remove_file and
create_dir by adding a "ffs_" prefix for these four functions.

Changes in v3:
- Change renaming from <ffs_camel_case_example> to <camel_case_example>

Changes in v2:
- Add email recipients according to get_maintainer.pl
- Add patch versions
- Use in-reply-to
