Subject: [PATCH] mhi: pci_generic: Fix implicit conversion warning
commit 4ea6fa2cb921cb17812501a27c3761037d64a217 upstream.
Fix the following warning with explicit cast:
warning: implicit conversion from 'unsigned long long' to
'dma_addr_t' (aka 'unsigned int')
mhi_cntrl->iova_stop = DMA_BIT_MASK(info->dma_data_width);
Fixes: 855a70c12021 ("bus: mhi: Add MHI PCI support for WWAN modems")
