From 52e4a5a989a4ef174e1ecb1b20d1902543298f9b Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 25 Apr 2025 23:15:27 -0700 Subject: [PATCH] media: iris: Cast iris_hfi_gen2_get_instance() allocation type In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct iris_inst *", but the returned type is "struct iris_inst_hfi_gen2 *". The allocation is intentionally larger as the first member of struct iris_inst_hfi_gen2 is struct iris_inst, so this is by design. Cast the allocation type to match the assignment.
