Description SMASH SMASH 2024-04-04 11:33:38 UTC

In the Linux kernel, the following vulnerability has been resolved:

Fix memory leak in posix_clock_open()

If the clk ops.open() function returns an error, we don't release the
pccontext we allocated for this clock.

Re-organize the code slightly to make it all more obvious.
