Summary
OPP: Fix potential null ptr dereference in dev_pm_opp_get_required_pstate()
Details

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

OPP: Fix potential null ptr dereference in devpmoppgetrequired_pstate()

"opp" pointer is dereferenced before the ISERRORNULL() check. Fix it by removing the dereference to cache opptable and dereference it directly where opp_table is used.

This fixes the following smatch warning:

drivers/opp/core.c:232 devpmoppgetrequiredpstate() warn: variable dereferenced before ISERR check 'opp' (see line 230)
