commit 7a64cd887fdb97f074c3fda03bee0bfb9faceac3 upstream.
There's one point was missed in the patch commit da49889deb34 ("staging: binder: Support concurrent 32 bit and 64 bit processes."). When configure BINDER_IPC_32BIT, the size of binder_uintptr_t was 32bits, but size of void * is 64bit on 64bit system. Correct it here.
