There's a check at ia_css_vf_configure() to verify if binary is not null. However, this is called too late: drivers/staging/media/atomisp/pci/atomisp2/css2400/isp/kernels/vf/vf_1.0/ia_css_vf.host.c:133 ia_css_vf_configure() warn: variable dereferenced before check 'binary' (see line 129) This test is wrong, as this fuction is only called by ia_css_binary_fill_info(), in a place that already assumes that binary is not null, and checks with: assert(binary != NULL); So, remove the useless broken extra check.
