| H A D | opal-imc.c | cb094fa5 Tue May 22 04:12:34 CDT 2018 Anju T Sudhakar <anju@linux.vnet.ibm.com> powerpc/perf: Rearrange memory freeing in imc init
When any of the IMC (In-Memory Collection counter) devices fail
to initialize, imc_common_mem_free() frees set of memory. In doing so,
pmu_ptr pointer is also freed. But pmu_ptr pointer is used in subsequent
function (imc_common_cpuhp_mem_free()) which is wrong. Patch here reorders
the code to avoid such access.
Also free the memory which is dynamically allocated during imc
initialization, wherever required.
