Subject: [PATCH v4 01/11] staging: r8188eu: use Linux kernel variable naming
convention
Follow the Linux Kernel coding style variable naming convention instead
of using camelCase style. Issue reported by checkpatch script for
these variables:
tagLen, tagType, networkAddr, ipAddr, macAddr
Signed-off-by: Deepak R Varma <drv@...lo.com>
---
Changes in v4:
1. Implement "use short variable name" feedback from David.Laight@...LAB.COM
Changes in v3:
-- None
Changes in v1 [actually v2]:
1. Improve patch description per feedback from julia.lawall@...ia.fr
