Hi all,

After merging the rdma tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

In file included from include/linux/kernel.h:14:0,
                 from include/asm-generic/bug.h:18,
                 from arch/powerpc/include/asm/bug.h:128,
                 from include/linux/bug.h:5,
                 from arch/powerpc/include/asm/mmu.h:126,
                 from arch/powerpc/include/asm/lppaca.h:36,
                 from arch/powerpc/include/asm/paca.h:21,
                 from arch/powerpc/include/asm/current.h:16,
                 from include/linux/mutex.h:14,
                 from drivers/infiniband/hw/cxgb4/iw_cxgb4.h:34,
                 from drivers/infiniband/hw/cxgb4/cq.c:33:
drivers/infiniband/hw/cxgb4/cq.c: In function '__c4iw_poll_cq_one':
include/linux/printk.h:308:2: warning: 'cqe.header' may be used uninitialized in this function [-Wmaybe-uninitialized]
  printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__)
  ^~~~~~
drivers/infiniband/hw/cxgb4/cq.c:674:16: note: 'cqe.header' was declared here
  struct t4_cqe cqe;
                ^~~

Introduced by commit

  4ab39e2f98f2 ("RDMA/cxgb4: Make c4iw_poll_cq_one() easier to analyze")

I can't tell easily if this is a false positive or not.
