[ Upstream commit 70d99623d5c11e1a9bcc564b8fbad6fa916913d8 ]
The DPLL_CLOCK_QUALITY_LEVEL_ITU_OPT1_EPRC is not reported via netlink due to bug in dpll_msg_add_clock_quality_level(). The usage of DPLL_CLOCK_QUALITY_LEVEL_MAX for both DECLARE_BITMAP() and for_each_set_bit() is not correct because these macros requires bitmap size and not the highest valid bit in the bitmap.
Use correct bitmap size to fix this issue.
