From: Dan Carpenter Date: Wed, 14 Jun 2017 10:44:51 +0000 (+0300) Subject: iwlwifi: missing error code in iwl_trans_pcie_alloc() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2388bd7b133504fa0991f483db66fad3a0de8694;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: missing error code in iwl_trans_pcie_alloc() We don't set the error code here so we end up returning ERR_PTR(0) which is NULL. The caller doesn't expect that so it results in a NULL dereference.
