Subject: [PATCH v1 3/3] lib/vsprintf: Force type of flags for gfp_t
Date: Fri, 31 Jul 2020 15:31:45 +0300	[thread overview]
Message-ID: <20200731123145.22357-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200731123145.22357-1-andriy.shevchenko@linux.intel.com>

Sparse is not happy about restricted type being assigned:
  lib/vsprintf.c:1940:23: warning: incorrect type in assignment (different base types)
  lib/vsprintf.c:1940:23:    expected unsigned long [assigned] flags
  lib/vsprintf.c:1940:23:    got restricted gfp_t [usertype]

Force type of flags to make sparse happy.
