drivers/macintosh/smu.c: Improve error handling
This makes two changes: * As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b, alloc_bootmem never returns NULL and always returns a zeroed region of memory. Thus the error checking code and memset after the call to alloc_bootmem are not necessary. * The old error handling code consisted of setting a global variable to NULL and returning an error code, which could cause previously allocated resources never to be freed. The patch adds calls to appropriate resource deallocation functions. Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Paul Mackerras <paulus@samba.org>
