This patch fixes following sparse warnings: drivers/staging/gdm724x/gdm_mux.c:389:32: warning: incorrect type in assignment (different base types) drivers/staging/gdm724x/gdm_mux.c:389:32: expected unsigned int [unsigned] start_flag drivers/staging/gdm724x/gdm_mux.c:389:32: got restricted __le32 [usertype] <noident drivers/staging/gdm724x/gdm_mux.c:390:29: warning: incorrect type in assignment (different base types) drivers/staging/gdm724x/gdm_mux.c:390:29: expected unsigned int [unsigned] seq_num drivers/staging/gdm724x/gdm_mux.c:390:29: got restricted __le32 [usertype] <noident> drivers/staging/gdm724x/gdm_mux.c:391:34: warning: incorrect type in assignment (different base types) drivers/staging/gdm724x/gdm_mux.c:391:34: expected unsigned int [unsigned] payload_size drivers/staging/gdm724x/gdm_mux.c:391:34: got restricted __le32 [usertype] <noident> drivers/staging/gdm724x/gdm_mux.c:392:33: warning: incorrect type in assignment (different base types) drivers/staging/gdm724x/gdm_mux.c:392:33: expected unsigned short [unsigned] packet_type drivers/staging/gdm724x/gdm_mux.c:392:33: got restricted __le16 [usertype] <noident> Sparse found above warnings, so this patch changes variable types of structs. Because expected and got variable types are different.
