Fixes undefined behavior where SDCardBlockDevice::wait_for_completition() runs off the end without returning a value.
The size of large block devices overflows when these variables are 32 bits long. For example, a 32 GB SD Card is reported as smaller than it really is.
The sd_card_info.sector_count and sd_card_info.sector_size_bytes variables are both 32 bit, so the multiplication overflows for large block devices.
|
Also fixes an overflow in the reported size of block devices by changing the data type to 64 bits and by preventing a multiplication overflow. |
