$ git grep -P -n '__section\s*\(\s*\"'
arch/arm64/mm/mmu.c:45:u64 __section(".mmuoff.data.write") vabits_actual;
include/linux/compiler.h:211:   __section("___kentry" "+" #sym )                        \
include/linux/export.h:133:     static int __ksym_marker_##sym[0] __section(".discard.ksym") __used
include/linux/srcutree.h:127:           __section("___srcu_struct_ptrs") = &name

My recollection is I submitted a patch
to _add_ quotes
