These two patches fix two coding style problems for all files under
drivers/staging/qlge as reported by checkpatch.pl,
- trailing */ in block comment
- unnecessary else after return or break
Coiby Xu (2):
fix trailing */ in block comment
fix else after return or break

Should we also replace all pr_errs with netdev_err in ql_dump_* functions? I'm not sure how we will use ql_dump_*. For example, ql_dump_regs is not referred by any kernel source, so I guess it's for the sole purpose of debugging the driver by the developer. But one pr_err in ql_dump_routing_entries which is called by dl_dump_regs doesn't prints out the device name whereas the other does, > void ql_dump_routing_entries(struct ql_adapter *qdev) > { > int i; > u32 value; > > i = ql_sem_spinlock(qdev, SEM_RT_IDX_MASK); > if (i) > return; > for (i = 0; i < 16; i++) { > value = 0; > if (ql_get_routing_reg(qdev, i, &value)) { > pr_err("%s: Failed read of routing index register\n", > __func__); > break; > } > if (value) > pr_err("%s: Routing Mask %d = 0x%.08x\n", > qdev->ndev->name, i, value); > } -- Best regards, Coiby ^ permalink raw reply [flat|nested] 19+ messages in thread
