load_nls() take a char * parameter, use it to find nls module in list or construct the module name to load it. This change make load_nls() take a const parameter, so we don't need do some cast like this: ses->local_nls = load_nls((char *)ctx->local_nls->charset); Suggested-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Winston Wen <wentao@uniontech.com> Reviewed-by: Paulo Alcantara <pc@manguebit.com> --- fs/nls/nls_base.c | 4 ++-- include/linux/nls.h | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-)
