Subject: [PATCH 0/2][RFC] mmc: cast to avoid unexpected error

Hi Ulf

These 2 patches adds cast to avoid unexpected error.
It tries copy to u64 without cast.
The data will be 0xfff... if 1st bit was 1.
These are reported by coverity tool, but I couldn't test it.
So, I added [RFC] on these patches.
I'm happy if someone tests it, or can get deep review.

Kuninori Morimoto (2):
      mmc: cast u8 to unsigned long long to avoid unexpected error
      mmc: cast unsigned int to typeof(sector_t) to avoid unexpected error
