Title
clocksource/drivers/cadence-ttc: Fix memory leak in ttc_timer_probe
Summary
In the Linux kernel, the following vulnerability has been resolved:
clocksource/drivers/cadence-ttc: Fix memory leak in ttc_timer_probe
Smatch reports:
drivers/clocksource/timer-cadence-ttc.c:529 ttc_timer_probe()
warn: 'timer_baseaddr' from of_iomap() not released on lines: 498,508,516.
timer_baseaddr may have the problem of not being released after use,
I replaced it with the devm_of_iomap() function and added the clk_put()
function to cleanup the "clk_ce" and "clk_cs".
Severity
No CVSS data available.
