Subject: mmc: debugfs: Print ext_csd in ascending order
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6780162c0097915dbc4e8fc11af662a270093d85;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mmc: debugfs: Print ext_csd in ascending order

ext_csd exported through debugfs is printed in reverse order (from
byte 511 to 0), which causes confusion.
Fix the for loop to print ext_csd in natural order.
