From: Changming Liu <liu.changm@northeastern.edu>

This patch series changes all appropriate instances 
of signed char arrays or buffer to unsigned char.

For each patch, if changing one variable to u8
involves its callers/callees, then those changes
are included in that patch as well.

Arrays explicitly noted as string are not changed
for the sake of readability. 

Changming Liu (6):
   USB: sisusbvga: change char to u8 for sisusb_copy_memory
   USB: sisusbvga: change sisusb_write_mem_bulk 
   USB: sisusbvga: change sisusb->ibuf,obuf,font_backup
   USB: sisusbvga: change userbuffer for sisusb_recv_bulk_msg to u8 
   USB: sisusbvga: change sisusb_read_mem_bulk
   USB: sisusbvga: change the local char array to u8 array

From: Changming Liu <liu.changm@northeastern.edu>

sisusb_copy_memory is called in several places.

sisusb_copy_memory calls sisusb_write_mem_bulk which 
is called by sisusb_write and sisusb_send_bulk_msg.

change the related parameters from char to u8 accordingly

From: Changming Liu <liu.changm@northeastern.edu>

isusb_write_mem_bulk calls sisusb_send_bulk_msg and 
is called by sisusb_write.
Changed their parameters accordingly.

Also change the local buf[4] of sisusb_write_mem_bulk
to u8. This fixed a potential undefined behavior.

Also it's called by sisusb_read_memory sisusb_testreadwrite

These arrays/data elements are used as unsigned.
So change them from char to u8.
