Subject: include/linux/property.h: fix build issues with gcc-4.4.4
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d76eebfa175e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

include/linux/property.h: fix build issues with gcc-4.4.4

gcc-4.4.4 has problems with initialization of anonymous unions:

drivers/mfd/intel-lpss-acpi.c:30: error: unknown field 'value' specified in initializer

work around this by crafting the initializers in a manner which the
compiler can handle.
