[PATCH v2] usb: dwc3: core: move dwc3_cache_hwparams before dwc3_alloc_event_buffers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



commit 392142 (moved event buffer allocation out of dwc3_core_init()). But
event buffer allocation uses the cached copy of hwparams to determine
the number of event buffers and the caching is done in dwc3_core_init.
So moved dwc3_cache_hwparams function before dwc3_alloc_event_buffers so
that dwc3_alloc_event_buffers sees the correct number of event buffers.
