Subject: iwlwifi: spaces in procfs filenames ?

    iwlwifi: pcie: give a meaningful name to interrupt request

perhaps unintentionally for file:

drivers/net/wireless/intel/iwlwifi/pcie/internal.h
in function static inline const char *queue_name

creates spaces in procfs filenames.

drivers/net/wireless/intel/iwlwifi/pcie/internal.h:static inline const char *queue_name(struct device *dev,
drivers/net/wireless/intel/iwlwifi/pcie/internal.h-                                  struct iwl_trans_pcie *trans_p, int i)

drivers/net/wireless/intel/iwlwifi/pcie/internal.h-     if (trans_p->shared_vec_mask) {

drivers/net/wireless/intel/iwlwifi/pcie/internal.h-

drivers/net/wireless/intel/iwlwifi/pcie/internal.h-     }

drivers/net/wireless/intel/iwlwifi/pcie/internal.h-}

# find /proc/ | grep " "
/proc/irq/130/iwlwifi: default queue
/proc/irq/131/iwlwifi: queue 1
/proc/irq/132/iwlwifi: queue 2
/proc/irq/133/iwlwifi: queue 3
/proc/irq/134/iwlwifi: queue 4
/proc/irq/135/iwlwifi: exception

Can these names be changed back or collapsed
to avoid the space use in procfs?
