[PATCH net-next] net: cdc_ncm: remove set but not used variable 'ctx'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/usb/cdc_ncm.c: In function 'cdc_ncm_status':
drivers/net/usb/cdc_ncm.c:1603:22: warning:
 variable 'ctx' set but not used [-Wunused-but-set-variable]
  struct cdc_ncm_ctx *ctx;

It not used any more after
commit fa83dbeee558 ("net: cdc_ncm: remove redundant "disconnected" flag")
