312466aaf8 Prevent setting zero over than bound
The &cmd will return a pointer which point to a pointer of cmdline.
It is a memory address which is usually 8 bytes in 64 bits machine.

However, the struct cmdline is 4 bytes. This will cause setting zero
beyond the bound.

Below is a simple example to show the differentiation:

struct cmdline {
        char skip_initramfs;
        char slot[3];
};

static void parse_cmdline(struct cmdline *cmd)
{
        printf("%lu\n", sizeof(*cmd)); /* 4 */
        printf("%lu\n", sizeof(&cmd)); /* 8 */
}

int main()
{
        struct cmdline cmd;
        parse_cmdline(&cmd);
        return 0;
}

This patch prevents this.

a7ceb04cb7 Fix early mount on S9/S9+
Unlike other common OEMs, Samsung use uppper case partition name.

e.g: /dev/block/platform/11120000.ufs/by-name/SYSTEM

This will cause setup_block() fails to find a match partition.
Thus, we should use strcasecmp instead of strcmp.

b3cd83bbca magiskinit: Only unmount /system and /vendor if it was mounted by magisk
This fixes an issue where if /system or /vendor was already mounted
prior to magiskinit running, then they would get unmounted.
