From eef31718ebfa6b56f9d32ff25110ede982abecdc Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Mon, 9 Dec 2013 09:47:46 +0200 Subject: [PATCH 01/28] iwlwifi: pcie: clean up ICT allocation code Since iwl_trans_pcie_alloc_ict is called in the PCIe allocation code, we always set CSR_INT_BIT_RX_PERIODIC. Move that bit to the default list of interrupts we enable and simplify the code. Also use dma_zalloc_ and avoid to memset the memory afterwards. trans_pcie->ict_index is 0 since trans_pcie has just been kzalloced, remove the redundant assignment.
