io_uring: fix warnings on shadow variables
There are a few of those: io_uring/fdinfo.c:170:16: warning: declaration shadows a local variable [-Wshadow] 170 | struct file *f = io_file_from_index(&ctx->file_table, i); | ^ io_uring/fdinfo.c:53:67: note: previous declaration is here 53 | __cold void io_uring_show_fdinfo(struct seq_file *m, struct file *f) | ^ io_uring/cancel.c:187:25: warning: declaration shadows a local variable [-Wshadow] 187 | struct io_uring_task *tctx = node->task->io_uring; | ^ io_uring/cancel.c:166:31: note: previous declaration is here 166 | struct io_uring_task *tctx, | ^ io_uring/register.c:371:25: warning: declaration shadows a local variable [-Wshadow] 371 | struct io_uring_task *tctx = node->task->io_uring; | ^ io_uring/register.c:312:24: note: previous declaration is here 312 | struct io_uring_task *tctx = NULL; | ^ and a simple cleanup gets rid of them. For the fdinfo case, make a distinction between the file being passed in (for the ring), and the registered files we iterate. For the other two cases, just get rid of shadowed variable, there's no reason to have a new one. Signed-off-by: Jens Axboe <axboe@kernel.dk>
