From 2bd30b8dc75b823dd7bbef9d7bc68e1fd7ecee5c Mon Sep 17 00:00:00 2001 From: Sang-Heon Jeon Date: Mon, 24 Aug 2026 01:18:14 +0900 Subject: coccinelle: alloc_cast: drop removed allocators - pci_alloc_consistent() and pci_zalloc_consistent() were removed by commit 7968778914e5 ("PCI: Remove the deprecated "pci-dma-compat.h" API") - kmem_alloc() was removed by commit f078d4ea8276 ("xfs: convert kmem_alloc() to kmalloc()") - kmem_zalloc() was removed by commit 10634530f7ba ("xfs: convert kmem_zalloc() to kzalloc()") - kmem_zone_alloc() and kmem_zone_zalloc() were removed by commit bae633a4a283 ("xfs: remove xfs_zone_{alloc,zalloc} helpers") So drop them from the rules. No functional change.
