Commit 92263a84 introduced mwifiex_deaggr_sdio_pkt which initializes variable pkt_type but does not use it. Compiling with W=1 gives the following warning, fix it. mwifiex/sdio.c: In function ‘mwifiex_deaggr_sdio_pkt’: mwifiex/sdio.c:1198:6: warning: variable ‘pkt_type’ set but not used [-Wunused-but-set-variable] Fixes: 92263a84 ("mwifiex: add SDIO rx single port aggregation") Cc: Zhaoyang Liu <liuzy@marvell.com> Cc: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by:

mwifiex_sdio_resume() intializes pm_flag, just like mwifiex_sdio_suspend(), but does not use it. Compiling with W=1 gives the following warning, fix it. mwifiex/sdio.c: In function ‘mwifiex_sdio_resume’: mwifiex/sdio.c:234:16: warning: variable ‘pm_flag’ set but not used [-Wunused-but-set-variable] sdio_get_host_pm_caps() is just an acessor, so the call to it is safe to remove.

The report is valid: doing the math in this function, with an input value N=63 the variable s16tableIndex gets a value of 31. This value is used as an index in the array log_table with 32 entries. But the next line is: s16errorApproximation = (s16) qm_mulu16(u16offset, (u16) (log_table[s16tableIndex + 1] - log_table[s16tableIndex])); With s16tableIndex + 1 we are trying an out-of-bounds access to the array. The log_table array provides log2 values in q.15 format and the above statement tries an error approximation with the next value. To fix this issue add the next value to the array and update the comment accordingly. Signed-off-by:

In order to obtain retry count for a given rate we need to pass the full struct ieee80211_tx_info to the function setting the rate in he TX descriptor. This uncovered a huge bug where the old code would use struct ieee80211_rate.flags to test for rate parameters, which is always zero, instead of the flags value from struct ieee80211_tx_rate. Time to find a brown paper bag :( Signed-off-by:

The 8192eu suffered from two issues when reloading the driver. The same problems as with the 8723bu where REG_RX_WAIT_CCA bits 22 and 23 didn't get set in rtl8192e_enable_rf(). In addition it also seems prone to issues when setting REG_RF_CTRL to 0 intead of just disabling the RF_ENABLE bit. Similar to what was causing issues with the 8188eu. With this patch I can successfully reload the driver and reassociate to an APi with an 8192eu dongle. Signed-off-by:

The generic disable_rf() function clears bits 22 and 23 in REG_RX_WAIT_CCA, however we did not re-enable them again in rtl8723b_enable_rf() This resolves the problem for me with 8723bu devices not working again after reloading the driver. Signed-off-by:

A device running without RX package aggregation could return more data in the USB packet than the actual network packet. In this case the could would clone the skb but then determine that that there was no packet to handle and exit without freeing the cloned skb first. This has so far only been observed with 8188eu devices, but could affect others. Signed-off-by:

These are never NULL, so stop making people think they might be. I don't change this for SDIO because SDIO has a racy card-reset handler that reallocates this struct. I'd rather not touch that mess right now. Signed-off-by:

card->adapter gets initialized in mwifiex_register_dev(). As it's not cleared in mwifiex_unregister_dev(), we may end up accessing the memory which is already free in below scenario. Scenario: Driver initialization is failed due to incorrect firmware or some other reason. Meanwhile device reboot/unload occurs. This is safe, now that we've properly synchronized suspend() and remove() with the FW initialization thread; now that code can simply check for 'card->adapter == NULL' and exit safely. Signed-off-by:
