[ Upstream commit e18655cf35a5958fbf4ae9ca3ebf28871a3a1801 ]
GCC 15 introduces -Werror=unterminated-string-initialization by default,
this results in the following build error
fs/smb/server/smb_common.c:21:35: error: initializer-string for array of 'char' is too long [-Werror=unterminated-string-ini
tialization]
21 | static const char basechars[43] = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ_-!@#$%";
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
To this we are replacing char basechars[43] with a character pointer
and then using strlen to get the length.
