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.

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.

This fixes an issue where if /system or /vendor was already mounted
prior to magiskinit running, then they would get unmounted.
