Subject: [PATCH 7/9] fix: Adjust min/max for 32f_s32f_convert_8i kernel
X-Git-Tag: archive/raspbian/2.3.0-3+rpi1^2~6

[PATCH 7/9] fix: Adjust min/max for 32f_s32f_convert_8i kernel

This kernel used `CHAR_MIN` to determine the minimum value which may be
0. It is expected that this value is -127. Thus, we move to `INT8_MIN`.

Fix #390
