Subject: [PATCH 2/2] powerpc/papr_scm: Fix build error due to wrong printf specifier
Date: Fri, 16 Apr 2021 21:12:09 +1000
Message-ID: <> (raw)
In-Reply-To: <>

When I changed the rc variable to be long rather than int64_t I
neglected to update the printk(), leading to a build break:

  arch/powerpc/platforms/pseries/papr_scm.c: In function 'papr_scm_pmem_flush':
  arch/powerpc/platforms/pseries/papr_scm.c:144:26: warning: format
    '%lld' expects argument of type 'long long int', but argument 3 has
    type 'long int' [-Wformat=]

Fixes: 75b7c05ebf90 ("powerpc/papr_scm: Implement support for H_SCM_FLUSH hcall")
