Subject: iwlwifi: do not use GFP_DMA in iwl_tx_queue_init
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=49898852e6aa8a6de9a5bc0bab2cf305b3583bbf;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

iwlwifi: do not use GFP_DMA in iwl_tx_queue_init

GFP_DMA is not necessary for the iwlwifi hardware and it can cause
allocation failures and/or invoke the OOM killer on lots of systems.
