      prism54 checks for dma mapping errors by comparison returned address
      with zero, while pci_dma_mapping_error() should be used.

      wlcore/wl12xx: spi: fix NULL pointer dereference (Oops) · e47301b0
      Uri Mashiach 提交于
      Fix the below Oops when trying to modprobe wlcore_spi.
      The oops occurs because the wl1271_power_{off,on}()
      function doesn't check the power() function pointer.

      wlcore/wl18xx: fw logger over sdio · 3719c17e
      Shahar Patury 提交于
      Enable the FW Logger to work over the SDIO interface in addition to over UART
      interface. In the new design we use fw internal memory instead of packet ram
      that was used in older (wl12xx) design. This change reduces the impact on TP
      and stability.
      
      A new event was added to notify fw logger is ready for reading. Dynamic
      configuration to debugfs was added as well.
