| |
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kishon Vijay Abraham I <kishon@ti.com>
commit 3006dc8c627d738693e910c159630e4368c9e86c upstream.
pm_runtime_enable is being called after omap2430_musb_init. Hence pm_runtime_get_sync in omap2430_musb_init does not have any effect (does not enable clocks) resulting in a crash during register access. It is fixed here.
