Hello,
Our static analysis tool finds a possible uninitialized-variable access in the nxp driver in Linux 5.14.0-rc3:
At the beginning of the function lpc_eth_drv_probe(), the variable dma_handle is not initialized. If the following conditions are false, it remains uninitialized. 1304: if (use_iram_for_net(dev)) 1314: if (pldat->dma_buff_base_v == NULL)
However, it is accessed through: 1333: pldat->dma_buff_base_p = dma_handle;;
I am not quite sure whether this possible uninitialized-variable access is real and how to fix it if it is real. Any feedback would be appreciated, thanks!
