Subject: [PATCH] bus: mhi: core: debugfs: Use correct format specifiers for addresses
For exposing the addresses of read/write pointers and doorbell register,
let's use the correct format specifiers. This fixes the following issues
generated using W=1 build in ARM32 and reported by Kbuild bot:
All warnings (new ones prefixed by >>):
>> drivers/bus/mhi/core/debugfs.c:75:7: warning: format specifies type 'unsigned long long' but the argument has type 'dma_addr_t' (aka 'unsigned int') [-Wformat]
