Subject: [PATCH AUTOSEL 5.2 62/85] uapi linux/coda_psdev.h: move upc_req definition from uapi to kernel side headers

From: Mikko Rapeli <mikko.rapeli@....fi>

[ Upstream commit f90fb3c7e2c13ae829db2274b88b845a75038b8a ]

Only users of upc_req in kernel side fs/coda/psdev.c and
fs/coda/upcall.c already include linux/coda_psdev.h.

Suggested by Jan Harkes <jaharkes@...cmu.edu> in
  https://lore.kernel.org/lkml/20150531111913.GA23377@cs.cmu.edu/

Fixes these include/uapi/linux/coda_psdev.h compilation errors in userspace:

  linux/coda_psdev.h:12:19: error: field `uc_chain' has incomplete type
  struct list_head    uc_chain;
                   ^
  linux/coda_psdev.h:13:2: error: unknown type name `caddr_t'
  caddr_t             uc_data;
  ^
  linux/coda_psdev.h:14:2: error: unknown type name `u_short'
  u_short             uc_flags;
  ^
  linux/coda_psdev.h:15:2: error: unknown type name `u_short'
  u_short             uc_inSize;  /* Size is at most 5000 bytes */
  ^
  linux/coda_psdev.h:16:2: error: unknown type name `u_short'
  u_short             uc_outSize;
  ^
  linux/coda_psdev.h:17:2: error: unknown type name `u_short'
  u_short             uc_opcode;  /* copied from data to save lookup */
  ^
  linux/coda_psdev.h:19:2: error: unknown type name `wait_queue_head_t'
  wait_queue_head_t   uc_sleep;   /* process' wait queue */
  ^
