Subject: [PATCH 0/2] ublk: specify io_cmd_buf pointer type

io_cmd_buf points to an array of ublksrv_io_desc structs but its type is
char *. Indexing the array requires an explicit multiplication and cast.
The compiler also can't check the pointer types.

Change io_cmd_buf's type to struct ublksrv_io_desc * so it can be
indexed directly and the compiler can type-check the code.

Make the same change to the ublk selftests.

Caleb Sander Mateos (2):
  ublk: specify io_cmd_buf pointer type
  selftests: ublk: specify io_cmd_buf pointer type
