Subject[PATCH] io_uring: Use ERR_CAST() instead of ERR_PTR(PTR_ERR())
Date
From: Changcheng Deng <deng.changcheng@zte.com.cn>

Use ERR_CAST() instead of ERR_PTR(PTR_ERR()).
This makes it more readable and also fix this warning detected by
err_cast.cocci:
./fs/io_uring.c: WARNING: 3208: 11-18: ERR_CAST can be used with buf
