Subject: io_uring: Use ERR_CAST() instead of ERR_PTR(PTR_ERR())
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=898df2447b9ee8d759e85d33087505d3905bf2f0;p=linux.git

io_uring: Use ERR_CAST() instead of ERR_PTR(PTR_ERR())

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
