[ Upstream commit 1c2b1049af3f86545fcc5fae0fc725fb64b3a09e ]
devm_kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.
Release the id allocated in 'mmdc_pmu_init' when 'devm_kasprintf'
return NULL
