From 66923a60ad80a963c0cd5ceecba9ba377cefba47 Mon Sep 17 00:00:00 2001 From: Saurabh Sengar Date: Sun, 24 Jan 2016 12:24:06 +0530 Subject: qe: Use GFP_ATOMIC while spin_lock_irqsave is held cpm_muram_alloc_common is called twice and both the times spin_lock_irqsave is held. Using GFP_KERNEL can sleep in spin_lock_irqsave context and cause deadlock Signed-off-by: Saurabh Sengar Signed-off-by: Scott Wood --- drivers/soc/fsl/qe/qe_common.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/soc/fsl') diff --git a/drivers/soc/fsl/qe/qe_common.c b/drivers/soc/fsl/qe/qe_common.c index e18159acfe45..41eff805a904 100644 --- a/drivers/soc/fsl/qe/qe_common.c +++ b/drivers/soc/fsl/qe/qe_common.c @@ -121,7 +121,7 @@ static unsigned long cpm_muram_alloc_common(unsigned long size, goto out2; start = start - GENPOOL_OFFSET; memset_io(cpm_muram_addr(start), 0, size); - entry = kmalloc(sizeof(*entry), GFP_KERNEL); + entry = kmalloc(sizeof(*entry), GFP_ATOMIC); if (!entry) goto out1; entry->start = start; -- cgit v1.2.3-55-g7522
