This patch introduces patches for the custom kernel, as it is currently used for the Radxa Rock 5B. The patches fix two gcc compiler warnings, which result in a build error, if the kernel is used with gcc version 12. Since also the code of custom board drivers for WiFi support is affected, and no fixes are provided by the vendor, the custom WiFi support is disabled.

Subject: mm: page_alloc: fix building error on -Werror=array-compare
|
|
|
|
Arthur Marsh reported we would hit the error below when building kernel
|
|
with gcc-12:
|
|
|
|
CC mm/page_alloc.o
|
|
mm/page_alloc.c: In function `mem_init_print_info':
|
|
mm/page_alloc.c:8173:27: error: comparison between two arrays [-Werror=array-compare]
|
|
8173 | if (start <= pos && pos < end && size > adj) \
|
|
|
|
|
|
|
In C++20, the comparision between arrays should be warned.
