| H A D | udbg_16550.c | cd32e2dc Mon Nov 10 16:12:28 CST 2014 Anton Blanchard <anton@samba.org> powerpc: Fix bad NULL pointer check in udbg_uart_getc_poll()
We have some code in udbg_uart_getc_poll() that tries to protect
against a NULL udbg_uart_in, but gets it all wrong.
Found with the LLVM static analyzer (scan-build).
Fixes: 309257484cc1 ("powerpc: Cleanup udbg_16550 and add support for LPC PIO-only UARTs")
Signed-off-by: Anton Blanchard <anton@samba.org>
[mpe: Add some newlines for readability while we're here]
