Check ERROR when can't mount SD card

[Thanh Quang]

Hi all, I'm working with SD card. When I push SD card in slot, it work fine. I want to LOG some error mess when SD card don't exist. I test this code and the result is my module reboot
Help me with this problem, I need to know when SD card isn't inserted and of course others function still have to work fine
Thanks for your interest

Here my sdcard_mount() func:
