Peter Collingbourne d43652aac2 mmc: core: don't initialize block size from ext_csd if not present ... commit b503087445ce7e45fabdee87ca9e460d5b5b5168 upstream. If extended CSD was not available, the eMMC driver would incorrectly set the block size to 0, as the data_sector_size field of ext_csd was never initialized. This issue was exposed by commit 817046ecddbc ("block: Align max_hw_sectors to logical blocksize") which caused max_sectors and max_hw_sectors to be set to 0 after setting the block size to 0, resulting in a kernel panic in bio_split when attempting to read from the device. Fix it by only reading the block size from ext_csd if it is available.
