Subject: drm/i915: Pair va_copy with va_end in i915_error_vprintf
From: Mika Kuoppala <[email protected]>
commit 1d2cb9a54abc6e1d239f28f07661366d5662a94a upstream.
Each invocation of va_copy() must be matched by a corresponding
invocation of va_end() in the same function.
This regression has been introduced in
commit e29bb4ebbf000ff9ac081d29784a3331618f012e
