X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=62289ba27558553871fd047baadaaeda886c6a63;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git qed: Fix possible system hang in the dcbnl-getdcbx() path. qed_dcbnl_get_dcbx() API uses kmalloc in GFT_KERNEL mode. The API gets invoked in the interrupt context by qed_dcbnl_getdcbx callback. Need to invoke this kmalloc in atomic mode.
