hp_sdc_rtc: Don't use create_proc_read_entry()
Don't use create_proc_read_entry() as that is deprecated, but rather use proc_create_data() and seq_file instead. Signed-off-by: David Howells <dhowells@redhat.com> cc: Brian S. Julin <bri@calyx.com> cc: Helge Deller <deller@gmx.de> cc: linux-m68k@lists.linux-m68k.org Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
