drivers: android: correct the size of struct binder_uintptr_t for BC_DEAD_BINDER_DONE
[ Upstream commit 7a64cd887fdb97f074c3fda03bee0bfb9faceac3 ]
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.
