fs/9p/vfs_dir.c:219:8: style: Local variable 'retval' shadows outer variable [shadowVariable]
   int retval = file_write_and_wait_range(filp, 0, -1);
       ^

Having another retval decl is not needed, if the initialized 0 is overwritten by a non 0
value by the call to file_write_and_wait_ranget(), the function returns early.

Fixes: b67c64fb0143 ("fs/9p: Consolidate file operations and add readahead and writeback")
