2022-11-09staging: rtl8192u: remove redundant macro definitionsDeepak R Varma1-61/+0
Several ieee80211_* symbol names are extended with _rsl tag using macros. This is done to avoid a conflict when a similar symbol is already in use in another part of kernel and may lead to conflicts. However, most of these base symbol names are not found to being used anywhere in the code and hence are not useful today. These symbols are not used outside of the module and hence can be safely removed. The code continues to use the original symbol names.

2022-11-09staging: ks7010: Avoid clashing function prototypesGustavo A. R. Silva1-122/+126
When built with Control Flow Integrity, function prototypes between caller and function declaration must match. These mismatches are visible at compile time with the new -Wcast-function-type-strict in Clang[1]. Fix a total of 27 warnings like these: drivers/staging/ks7010/ks_wlan_net.c:2415:2: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, struct iw_point *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict] (iw_handler)ks_wlan_get_firmware_version,/* 3 KS_WLAN_GET_FIRM_VERSION */ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The ks_wlan_net Wireless Extension handler callbacks (iw_handler) use a union for the data argument. Actually use the union and perform explicit member selection in the function body instead of having a function prototype mismatch. There are no resulting binary differences before/after changes. These changes were made partly manually and partly with the help of Coccinelle. Link: https://reviews.llvm.org/D134831 [1] Signed-off-by: Gustavo A. R.

This driver is a single standalone driver and does not have any loading dependencies on another associated drivers. The build results in one single .ko object. The current implementation of the function ieee80211_tkip_null simply returns back to the caller without any useful instruction executions.

2022-11-02staging: octeon: cvmx_ptr_to_phys() should return physaddr_tGeert Uytterhoeven2-3/+3
On 32-bit without physical address extensions (e.g. sh-allmodconfig): drivers/staging/octeon/ethernet-mem.c: In function ‘cvm_oct_free_hw_memory’: ./arch/sh/include/asm/io.h:239:32: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 239 | #define phys_to_virt(address) ((void *)(address)) | ^ drivers/staging/octeon/ethernet-mem.c:123:18: note: in expansion of macro ‘phys_to_virt’ 123 | fpa = (char *)phys_to_virt(cvmx_ptr_to_phys(fpa)); | ^~~~~~~~~~~~ Fix this by making cvmx_ptr_to_phys() return physaddr_t instead of uint64_t.

2022-11-02staging: r8188eu: use ether_addr_equal in OnActionMartin Kaiser1-1/+1
Use ether_addr_equal to compare two mac addresses in OnAction. Both struct ieee80211_mgmt and struct eeprom_priv's mac_addr component are 2-byte aligned.

We can use ether_addr_equal instead of memcmp in update_recvframe_phyinfo_88e for comparing the incoming frame's destination address with our local address.
