From 017909281eb0f8a00445840a36c799d3aed00841 Mon Sep 17 00:00:00 2001 From: Martin Kaiser Date: Sun, 29 Nov 2020 19:52:28 +0100 Subject: [PATCH] mailbox: stm32-ipcc: cast void pointers to unsigned long Now that the driver can be enabled by COMPILE_TEST, we see warnings on 64bit platforms when void pointers are cast to unsigned int (and vice versa). warning: cast to smaller integer type 'unsigned int' from 'void *' unsigned int chan = (unsigned int)link->con_priv; ... warning: cast to 'void *' from smaller integer type 'unsigned int' ipcc->controller.chans[i].con_priv = (void *)i; Update these casts to use unsigned long variables, which are the same size as pointers on all platforms.
