Ivy Lopez 93a27367ba riscv: hwprobe: simplify has_fpu() to check D extension only ... The kernel never supports D without F, since D depends on F. The D-extension flag is cleared during devicetree/ACPI parsing whenever F is not present, so has_fpu() checking either extension with '||' never actually produces a different result than checking D alone - F without D cannot occur in practice, and there is no observable impact on RISCV_HWPROBE_IMA_FD or userspace. Simplify has_fpu() to check D only, matching the expectations set elsewhere in the kernel for this dependency, rather than relying on a redundant OR condition. sys_hwprobe.c already calls has_fpu() and needs no changes.
