media: atomisp: Fix eed1_8 code assigning signed values to an unsigned variable
ia_css_eed1_8_vmem_encode() is assigning values with a range of -8192 -
8191 to e_dew_enh_y and e_dew_enh_a both of which are of the VMEM_ARRAY
type which maps to u16.
This causes the following smatch warnings:
drivers/staging/media/atomisp/pci/isp/kernels/eed1_8/ia_css_eed1_8.host.c: drivers/staging/media/atomisp/pci/isp/kernels/eed1_8/ia_css_eed1_8.host.c:177 ia_css_eed1_8_vmem_encode() warn: assigning (-8192) to unsigned variable 'to->e_dew_enh_y[0][base + j]'
drivers/staging/media/atomisp/pci/isp/kernels/eed1_8/ia_css_eed1_8.host.c: drivers/staging/media/atomisp/pci/isp/kernels/eed1_8/ia_css_eed1_8.host.c:182 ia_css_eed1_8_vmem_encode() warn: assigning (-8192) to unsigned variable 'to->e_dew_enh_a[0][base + j]'
Convert the e_dew_enh_y and e_dew_enh_a arrays to a new SVMEM_ARRAY type
which maps to s16 to fix this.
