Subject: msm: camera: don't cut to 8bits for validating enum variable
|
||
|
|
||
|
In msm_ispif_is_intf_valid(),
|
||
|
we convert a enum variable msm_ispif_vfe_intf,
|
||
|
to uint8_t type for validating.
|
||
|
|
||
|
This could cause potential issue,
|
||
|
if the value is crafted in such a way that lower 8bits pass the validation.
|
||
|
|
||
|
Don't use uint8_t as input parm to avoid such vulnerability.
