remove unallocated partition

[Patrick Dupre]

Hello,

On one disk, I have an extended partition (sdc4) starting at 41338880
Inside, I have a ext4 partition (sdc5) starting at 53919744 (see attached file)
In between the space is unallocated

How can I make that the partition sdc4 starts just at the beginning of sdc5

Thanks
