[PATCH] hpet: fix uninitialized variable in hpet_register()
Clemens Ladisch [Sun, 30 Oct 2005 23:03:39 +0000 (15:03 -0800)]
Clear the ht_opaque field in the hpet_register() function before searching for
a free timer to prevent the function from incorrectly assuming that the search
succeeded afterwards.
