Hi all,
After merging the kspp tree, today's linux-next build (x86_64
allmodconfig) failed like this:
In file included from include/linux/bitops.h:33,
from include/linux/kernel.h:22,
from drivers/platform/x86/thinkpad_acpi.c:37:
drivers/platform/x86/thinkpad_acpi.c: In function 'tpacpi_dytc_profile_init':
arch/x86/include/asm/bitops.h:207:22: error: array subscript 'long unsigned int[0]' is partly outside array bounds of 'int[1]' [-Werror=array-bounds]
207 | (addr[nr >> _BITOPS_LONG_SHIFT])) != 0;
| ~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/platform/x86/thinkpad_acpi.c:10385:18: note: while referencing 'output'
10385 | int err, output;
| ^~~~~~
Actually the test_bit() in line 10409.
Caused by commit
e1c21608e3cf ("platform/x86: thinkpad_acpi: Add PSC mode support")
from the drivers-x86 tree interacting with the enablement of
-Werror=array-bounds.
I have reverted that commit for today.
