No. As your log, it has not yet tried to download firmware.

Since first rtw_pci_read32() from rtw_chip_info_setup() is
hal->chip_version = rtw_read32(rtwdev, REG_SYS_CFG1); // REG_SYS_CFG1 is 0xf0
So, I guess r1 is to store arg2 (REG_SYS_CFG1), and r3 is rtwpci->mmap + addr.

But weird. It says that is a vmalloc region.
I'm not familiar with the trace. Just point out some suspicious points for
reference.
