remoteproc: qcom: mdt_loader: Use signed type for offset
In the transition from using rproc_da_to_va(), the type of the load offset became unsigned. This causes the subsequent check to let negative values less than p_memsz + mem_size through and we write outside of the buffer. Change the type back to a signed value to catch this. Fixes: 7f0dd07a9b29 ("remoteproc: qcom: mdt_loader: Refactor MDT loader") Fixes: e7fd25226295 ("remoteproc: qcom: q6v5: Decouple driver from MDT loader") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Reported-by: Stanimir Varbanov <stanimir.varbanov@linaro.org> Acked-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
