Bojan Novković 6e8233df18 hwpmc_x86: Fix NULL deref when loading on unsupported hardware ... The pmc_md_{intialize, finalize} routines rely on a machine-dependent structure to register the appropriate PMC interrupt handler. However, the vendor-specific routines that allocate this structure may return NULL for unsupported hardware, leading to a panic when the hwpmc module gets loaded. This patch adds additional checks that fix this issue.
