Subject: pc-bios/s390-ccw: size_t should be unsigned
|
|
|
ae23c9 |
|
|
|
ae23c9 |
"size_t" should be an unsigned type according to the C standard.
|
|
|
ae23c9 |
Thus we should also use this convention in the s390-ccw firmware to avoid
|
|
|
ae23c9 |
confusion. I checked the sources, and apart from one spot in libc.c, the
|
|
|
ae23c9 |
code should all be fine with this change.
