isdn: hisax: callc: Replace GFP_ATOMIC with GFP_KERNEL in init_PStack()
init_PStack() is never called in atomic context. It calls kmalloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
